The heart beats about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.

If all arteries, veins, and capillaries of the human circulatory system were laid end to end, the total length would be 60,000 miles, or 100,000 km. That’s nearly two and a half times around the Earth!

Human hair grows about 1/4 inch (about 6 millimeters) every month and keeps on growing for up to 6 years. The hair then falls out and another grows in its place.

AntiChristian:
Of course not the Bible!

Neither did you read anywhere in the Bible that Cain and Abel slept with their sisters! Which would be a very important detail to leave out!
Neither did we read where the Chinese and their slanty eyes came from. Nor all these other races and their vast differences.
Actually, neither did we read that a law was passed whereby God could never create anything or anyone again!

AntiChristian:
Anyways, I have never read any report that Eve slept with any of his son or Adam with his daughters!

What I read is that Eve had twins many times and it was always a male and a female!

A male is required to marry the female of another pregnancy! Cain didn't like this arrangement as his own partner was prettier than Abel's.

So they had to make a sacrifice and Abel's was accepted!

Don't know where you read all this - definitely not in the Bible. The first set of twins in the Bible were Esau and Jacob.

EmiDon11:
if i say u no get sense now, u will think i am insulting you.

Abeg no vex. It’s just that this topic has been on Nairaland a million times and you were writing like it's some wonderful insight you had!

GreyLaw:
He shouldn't be. He will be sacked and nothing will happen. He should try hard between now and November to recoup the billions he wasted on tbe elections.

Sacked by who?? WHO EXACTLY will do it and WHAT EXACTLY will be the process?

Distracting us with nonsense to forget our suffering.
What a charade!

abobote:
21 year old girl, not woman

You, my friend, are WRONG!
The proper way to refer to any male or female who has attained the age of majority (18 in Nigeria) is
MAN or WOMAN.
Now you know!

noele:
Thank you very much for the recognition and kind words, sir/ma'am. You can locate the bank's name within the list of banks available in your application. Certain banking apps display PAYCOM as well.

Oh, ok. Thanks.
I read somewhere their MD ran away or they're out of business or something

AmbFitsaint:

Sooo, your mum's 55th birthday is around the corner.
How has she held up? And you? How you been doing?

noele:
Ahhh, what a pity.

Good PM N'Landers. I hope this message finds you all in good health. My name is Jumoke, and I find myself in a situation where I must humbly reach out to seek your support during these challenging times. I am a widow who recently lost my beloved husband in a tragic car crash. Coping with this loss has been overwhelming, especially as I am now solely responsible for providing for my precious baby and myself.

The impact of the ongoing economic difficulties, exacerbated by the removal of fuel subsidies, has further compounded my struggles. The ripple effects of this decision have resulted in a sharp rise in living costs, and I have found myself without a stable source of income. As a result, I am facing the heartbreaking challenge of being unable to afford basic necessities, particularly nutritious food for my baby and myself.

I understand that everyone is facing their own set of challenges, and I am truly grateful for any support, no matter how small, that you might be able to offer. Your generosity would alleviate the burden I am currently bearing and provide us with the sustenance we desperately need.

For your convenience, I have provided my Opay account details below:

OPAY Account Name: Jumoke
80 233 48 658

I want to assure you that any contribution you make will be used solely for the purpose of providing nourishment and care for my baby and me. If you are unable to contribute financially, your words of encouragement and support are equally valuable and deeply appreciated.

Thank you for taking the time to read my message, and I am hopeful that your kindness and empathy will help us through this difficult period.

With heartfelt gratitude,
Jumoke

Jumoke you write very well. I hope someone reads this and offers you a job as an editor or content creator - something you can do from home, from your phone.
Just curious, how do people send money to OPAY?

Oh, RIP to the poor girl. 21 years old at that!

Jakumo:
Not all women can be bought with money, as this story you've kindly posted about one of Elon Musk's failed seduction attempts aboard a private jet clearly illustrates.

The EU and USA count among their billionaires many who are tired of renting call girls, yet are so inept at the nuances of sparking female attraction that such men are often LONELY even as they relax amidst the opulent trappings of their eye-watering wealth.

The mother of Elon Musk's child has the appearance of a prepubescent child herself and is no beauty queen by any yardstick, suggesting that Elon Musk, who has described himself as being autistic in some regards, never developed the social skills needed to attract and marry a quality woman of great beauty and intellect commensurate with Mr. Musk's towering social status as one of our planet's richest men.

Another famous billionaire whose bride is no beauty queen is Jeff Beezos of Amazon who recently became engaged to a middle-aged, plastic surgery-disfigured puffy-lipped woman that would never turn any heads at the beach, yet is now positioned to secure a multi-billion dollar divorce settlement just as soon as she can sink in her claws deeply enough. That very odd selection of a plain old pedestrian-looking woman with fish lips and hard plastic fake tits for a bride, suggests that Jeff Beezos, like Elon Musk, is also severely lacking in the seduction skills that are essential to any man seeking a high-quality woman for sex or marriage.

You make a good point.
But that Elon Musk sef, na mumu. Of all things to offer to buy a girl, na horse! I wonder if he had offered to buy her a house or give her a million...
Here are their ugly wives:

squash47:
everybody wants to form mancho man for social Media... For real life, Dem dey beg for love..

In real life some of us got women chasing US all because we got "game"!
No mind the OP, the only thing that gives real confidence (which is so attractive to women) is KNOWING the woman thinks you got what she wants! (you don't have to have it. She only has to THINK you do! )
"Sure, take care." is after the fact, doesn't give anybody confidence!

DaddyFreeze2020:
Women don't reject men that have money.
Ask Davido or Dangote.
Even married women will be happy to date Davido or Dangote.

You should say "Nigerian women". See below. And this was when he was worth 330 billion and Dangote worth 9 billion

Persephone1:
Of course they do but not on Nl I guess

You women too pretend. Go into a uni class and ask if any girl is looking for a boyfriend or husband. Not a single hand will rise!

Persephone1:
For a gender that doesn't care about a woman's orgasm, do not benefit from marriage, sees all women as golddiggers y'all ponder and type too much epistles on women

Go siddon. Pretenders. Women do it worse than men, except not on NL. Women that do nothing but gossip about men relationships all day long. At least men talk about a lot other things too!

Osoboshi:
this the realest game,n why love the work for,others money,others iphone.the game can't be universal

That's what Yahoo boys do They know what those women want and they present they're exactly that, and the women fall in "love" despite the poor grammar and thick accent!
You don't gotta be a Yahoo boy, but at least have some imagination!

Jakumo:
Going to the extent of blocking communication with a woman that INITIALLY rejected a man's advances would be a mistake because that initial rejection may well be a test of a man's patience and perseverance. Blocking communication indicates that ANGER due to rejection is the man's reason for closing channels of communication. Conveying bitterness as one's response to an initial rejection is the WRONG move.

Certainly, rejection calls for a toning down of the initial romantic approach along with perhaps a temporary radio silence from the man, BUT there should be no blocking of the woman's usual channels to reach out LATER, since she may very well do so after seeing the man pass her "no desperation" and 'strong self-esteem" test. It is possible for a woman who rejected a man as a test, to be back engaging him in highly suggestive online flirtation within DAYS of that purported rejection.

You nailed it.
Women that change their minds constantly and are not really sure what they want. A woman may say no to you this minute and regret it the next minute - and you already bocked all means of communication??

Jovialjune1:
Una no dey ever tire? Na frustration dey cause all this long epistle ontop woman matter, na wa.

Go siddon. Pretenders. Women do it worse than men, except not on NL. Women that do nothing but gossip about men relationships all day long. At least men talk about a lot other things too!

preciousee17:
In trying to be wise, the OP actually displayed too much ignorance

He called it big question of the day, with 3 exclamation marks!

AntiChristian:
They married their sisters as it wasn't forbidden then!

Eve too was made from Adam!

Neither was it forbidden that (nor do we know if) Eve had children with her sons, or Adam with his daughters - à la Lot and his daughters!

Anyway, I googled and saw this:

Wow, what an original question! The first person to ever ask this since creation. And he bolded it too, then called on nlfpmod to rush it to FP. You be real genius my friend.
Why not tell us, the genius you are, who did they marry?

GenderMix:
Says who?

The ultimatum ends by 12pm today. The Niger coupists won't give in.

By tomorrow expect heavy military presence from ECOWAS in Niger.

It looks like it's going to be a long ride

How much you wanna bet?
'slong as the populace support the coupists

DodadaKoKigbe:
You're not alone. Women armpit odor turns me on like crazy!

Goes the other way too if not more. Most women love the natural smell of a clean man doing some hard labour

You're 200% right. It is the biggest blunder in modern international doplomatic chess game!

I remember how everyone was kissing Putin's ass and begging him, heads of states going to Russia to beg him. He'd have gotten all sorts of concessions as long as everyone THOUGHT he could take Kyev in one day.
From being so esteemed he became a war criminal, and also exposed how ineffective Russian army really is!

Jennyclay:
I don’t drink any water aside Eva water or Aquafina water (Pepsi). I can’t remember the last time I even drank sachet pure water

You see Ore-Benin express road, 90% of the table water you buy there are packaged exactly this way directly from those dirty ore rivers . But Ore still remain the best place to buy banana, groundnut and plantain.

If I’m traveling by road, I make sure I hold enough Eva water that would last me for the journey before Nigerians poison me!!

People who fake Eva and Aquafina will be reading this and just laughing

youngsahito:
This girl needs to be arrested with her criminal in crime. Bottle water factory need to start sealing the nylon to know the fake product.

madridguy:
This is a false alarm against the innocent girl. From the video I don't anything that point that she will be selling the water.

Why she is refilling the plastics with water is best known to her but it is very far from hawking it.

Bvlgari:
Maybe u dey this dirty business too. Because what in your little shallow mind did u think she was gonna do with those many bottled water? Put in her fridge? Or share at their village meeting? U can see a man behind her also arranging his hawking stuffs and getting ready to hit the road for sales

Open mouth wahhhh defending nonsense. Better go sleep

There are 3 sides to every story.
How you know the OP is not telling the whole story is that it would have been VERY easy to show a video of the girl selling the water - but he couldn't do it!

Depends on how you look and also your age, I think.
You have to realise as an American they automatically think you have a lot of $, even if you really don't have.
So be mindful, no need to try to appear rich!

Good if you befriend a fellow traveler on the plane - a native. They'll give you ideas - appropriate amount tips and bribes to give and maybe lend you naira till you change some dollars in the lobby. As for phone, your helper will let you use his phone till you get yours, also there are carriers that you can use your phone anywhere in the world for a monthly fee.

Once you arrive and go to baggage area person/persons would come to try help you. Let one of them help you. They are known and monitored, it's also how they try to make a living, but still keep an eye out - don't overly trust anybody. You'd have to "tip" customs if you don't want them to ransack your bags.
Somehow find out in advance the right bribe amount.

Take one of the registered taxis that's registered to work at the airport and officially dispatched. You'd be safe. It's all quite safe - never mind the hype.

As for vegetarian food, good for you - you'd save money not eating meat. Simply order anything you want, rice, eba, dodo, and tell them not to put meat.

You'd enjoy your stay. Just go with the flow - don't try to solve Nigeria's corruption problem. "Tip" police officers where appropriate or necessary (of course in US that will land you in jail!).
Enjoy the culture shock and friendliness - Nigerians tend to like foreigners, especially westerners.

He makes lotsa sense

Bahamas95:
"Dem nor dey carry cutlass go gun fight"

They ain't same scenario, I don't waste my time chasing a woman that rejected me. I will jejely leave her alone and knock on the next door instead of belittling myself to one bleeding gender.

Point is, you shouldn't be "chasing" a woman in the first place. Leave that to agberoes and construction workers. Have game. Do your homework. Find out what that woman or women in that area want. Have it or present you have it, and they'll be the ones chasing you! You'd have the experience of a woman/women codedly chasing YOU!

Bahamas95:
100% correct.

VinnyBaba:
Kudos to you, OP.👍👍

Wish all Young Niggas in this Naija can see this.

Sooo, how come sales people end up talking people into buying something they initially said they'd absolutely not buy minutes before? They do their homework! They prepare their game well. The customer has no chance!

"Sure, take care" and that's the end of it? Na, not good.
Women that change their minds constantly and are not really sure what they want. A woman may say no to you this minute and regret it the next - and you already out of communication? Not good

Best thing anyway is, never approach girls for date directly. Otherwise you're already a loser. If you must, first build yourself up so much in her imagination and read her so well, she can't possibly say no!
But most people are lazy, no preparation at all, no imagination, just shot in the dark and hope for a miracle!

Good one OP, quite informative. And no clickbait
