Just a bit of silliness.
There is a test or call it a game of sorts.
You place a chair a few inches from the wall, with the back side toward the wall.
You stand in front of chair, bend forwards and touch your head on wall. You then reach down and pick up the chair, with head continuing to touch wall.
You then proceed to stand up while holding chair up.
In this test, almost all females can stand up without too much difficulty, males on the other hand have much difficulty or cannot even do it.
I took this test a few times in my life, the last time years ago at some gathering. I was never able to stand up, even if I was on my tippy toes.
I just tried it the other day. I did it with little effort. I did use my toes somewhat but unlike before even if I was on the tips of my toes I couldn't do it.
I am not taking this seriously, its all in fun, but I was and still am curious as too why this happens.

Maybe its the boobs!
