To All Singles,is It Too Much Ado About Nothing Or Smthn!

i was reading a medical thing on the net about the sturvs you need to do before getting married i.e knowing what blood group you and your partner both belong to,then making sure both you and her are hiv negative and also making sure theres no hereditary deseases in both your lineages
also thought about the moral issues like making sure you r both compatible,and that she ll be faithful, and none of you are barren e.t.c not to talk of the whole drama after you settle down.

i was thinking about all these and concluded that any single guy or girl is in for a lot of stress getting the right guy/girl especially when you think of some of the reasons i v listed above,whcih is the way foward and is there anyway to make it easier or just ignore some of it?
please try and share your thought if your single,either male or female and if you always think about these sturvs and your heart skips a few beats, me i do and my heart skips a bit o, no be small thing o
