You know, many years ago, I told my nephew that I could put clay on his skull and make him appear to be ape-like.
In the same way insects become immune to insecticides, I became immune to penicillin because I had massive doses when I was growing up. Do you think will my offspring also be immune to penicillin? Will it change their DNA?
What do you mean, "immune to penicillin"? Penicillin doesn't work by killing off your own cells, penicillin works by killing bacteria. Perhaps you have a strain of endemic bacteria that are now immune to penicillin, but you yourself wouldn't be.
Anyway, there's no evidence that I know of that any kind of environmental stress you encounter in your life will be passed on to your children's genes.
But there is growing evidence that you're afraid of filling out the survey in post 68. Why is that?
