Lol. And all my tattooed friends support mine.
Absolutely any major decision can be regretted, and people change all the time. Avoiding things you might regret is a recipe for never doing anything at all.
You could just as easily say, the person who chooses to go to college isn't the same person who's stuck paying the debt. People change, and I know a guy who regrets going to college - his goals changed and the field he studied no longer interests him.
Or, you should never have kids, because you're going to be stuck with them for, like, twenty years! What if you change during that time and you don't want to do the whole parent thing anymore - you try finding a clinic to laser off your five year old.
