But someone still has to raise the kid at some point, and besides, not everyone can make sperm.
I'm not sure that sperm banks have an oversupply; apparently England has something of a shortage due to its questionable decision to ban anonymous donation, which is why our David Gerard reports back that it was very easy to do even though he's old enough he wouldn't even be considered in the USA as far as I can tell.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
