There are a lot of plain arguments about what makes up a man(both sexes). Many have come out to claim being the strongest vessel and others have accepted to be the weaker. 
But only one thing makes these decisions true or untrue..."Circumstances."
Both male and female are legitimately stronger vessels depending on the circumstances at the moment. When you have a shoulder to fall back to when hurt, you're weak. But if there's no shoulder to lean on when you're hurt, you will be left with no other option than to be strong for your whole being/existence.
I know myself, I am strong!
Yeah...
What you choose to do in circumstances makes you
Yeah.. That's very true... I know of a man that cries like a baby when hurt. Lol
