The tigh is undoubtedly the longest bone. That we know from time immemorial. It might not necessarily be the hardest bone. Still. I stand to be corrected
Re: 40 Amazing Fact About Human Beings by kilojoDesigns: 5:59pm On Aug 24, 2017
hardest bone is the jaw bone
strongest bone is the thigh bone

op is right, since we tend to mix strong and hard up, the confusion comes up

Re: 40 Amazing Fact About Human Beings by kilojoDesigns: 6:04pm On Aug 24, 2017
what I think is that
strength here is measured by what it can do/carry or support , yes the hardness comes into play but the shape, size, positioning etc also largely contribute making the thigh bone the strongest.

while hardness here is just the overall density of the bone

That is very technical. Its the rounded part.

If you're observant in bushy places or in the wild, you'd notice there are many of those animal oval knee bones especially if there are dogs around the area.

I can totally attest to that number 22.A person loses their taste buds as one grows older.

Case study: u will be dreaming and promising yourself to eat over and over all those delicacies you were never fortunate to eat when you are young and poor. One will finally grow old and rich and you will lose the appetite for some certain food outrightly. That's the only viable explanation.
