I do think people who comment on it are probably just trying to encourage it because they themselves have found it to be one of the most rewarding things they have ever done, and maybe they had been hesitant before they did it. Also… people DO change their minds when they get older sometimes. But it certainly is a personal decision. I wouldn’t tell someone to do it who said they didn’t want to, but I wouldn’t be stunned if I found out 5 years later that they changed their minds, either.
