not if you have the proper constitution for such dining habits.
Oh no, the dining habits or constitution aren't the problem.  It's just that later on, eating too many tacos will come back to haunt you.  It could come in the form of a heart attack, high blood pressure, or even worse - castration. (Often, the buildup can take years, but sometimes it can come suddenly and unexpectedly.)  Tacos are the best, yet the worst.
Plus, the hot sauce always seems to get all over the place.
