I doubt its very likely that your kids can track you down. If they did, you could just tell them to be thankful you didn't wipe them on a tissue and to leave you alone.

I'd be down for doing this, I'm not planning on ever having my own kids, so someone else might as well have them for me. Unfortunately my family history would probably give cause to reject my "specimen". (one side riddled with cancer, the other side has heart disease and Alzheimer's...)
