I used to smoke cigarettes, ten a day, but gave up when I was 28. Now my vice is several cups of coffee a day, which isn't great if you're prone to weak bones as I am, as caffeine can leach calcium.
Everybody in my band is married, pretty much, and have lives at home, and I don't want them to be away from their families so long that they just start to feel psychotic. You have to go home and stand around in your bathrobe doing your dishes to feel like a normal person sometimes.
