TM: I am sorry you feel bad. What was evolution thinking?
What, indeed? If evolution is trying to convince me that 9 months of pregnancy and its attendant woes is a worthwhile tradeoff to avoid the monthly Communist Incursion, evolution's got another thing coming. If this is evolutions way of telling me I wouldn't be in such pain had I been pregnant when I was younger and healthier, well, that's not helpful either- it's not like I can do anything about it now.
I would like to evolve a non-cramping uterus. And a prehensile tongue, but that's another story.
