A commenter on Mike's blog requested a debate on age limits. Since Mike hasn't put it up yet, I will. So.
A recent study showed that under-21 college students were likely to binge drink on all campuses studied except one: McGill in Montreal, where the drinking age is 18. Age limits on drinking are obviously a spectacular failure. Age limits encourage immature behavior in those under the arbitrary age selected and should be abolished. This goes for things like drinking, sexual consent, contracts, R-rated movies (not the advisory rating system, just the laws), etc. (In the case of sexual consent, I could get behind a limit that coincided with the one that God has imposed upon us.)
