Spotted the following argument in a story about the Texas state senate approving a bill to raise the legal age to buy cigarettes up a year:

“The further you can put this (legal age) off, there’s a much better chance that people will not start to smoke,” said Sen. Carlos Uresti, D-San Antonio.

Ponder that for a moment, then ask yourself this: if Carlos’ reasoning were taken seriously, what would be the barrier between raising the age to 19 and, say, raising it to some arbitrary higher number like 40 or 50?
