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.
I discovered the 7th art at home when I was kid, through Charlie Chaplin's movies and those of my father who shot documentaries. He was my biggest influence. So I took his camera and started shooting.
