Either way, this will still help couples who DEFINITELY don't want kids. Just helps chances.

120 - 60 = 60.
They are expected to live until you are 60.

It would help couples out a lot, you know. I think birth control is one of the best inventions on this planet.

Well, sixty isn't such a bad age to lose your parents... Though I think most people lose their parents before that age.

Average age of a child at parent death is 40. so unless parents give birth during teen years I doubt that.

If the average age of a parent is 24 and the average age of death is
64 then the average age of a child on the death of a parent would be
40.

That's not that bad, I mean you'd be sad but it's not as thought your off to live in an orphanage (or under the stairs of your aunt and uncles place).

I'm thinking that I want to see more testing and peer-reviewing before I take a pill that screws around with little Rutten.

I want to keep fertility at the same time not permanently sterile...
So give it to my friend first.
