I am sorry, but I think every adult in the western world should know about it. So obviously not little brother safe if your brother can read.
In the 1980s, I read some cyber-punk stories. Those were really scary, really cynical stories about what the future might be like. One was about a guy who had had so many children through donating sperm that he wasn't sure how many children he had had, and he couldn't be sure the women he picked up for a good time weren't own his daughters. This is worse.
Incidentally, my American readers' president, the former Junior Senator from Illinois, voted against a ban on so-called "partial birth" you-know-what on more than one occasion. I wonder if someone hadn't explain to him the commercial value of such butchery.
Update: I guess the whatsit-rights people have to go beyond "It's just a clump of cell" now. Now they'll have to say "It's just a clump of tissue--with a head, liver, lungs..."
