I quit drinking for health reasons and am 61 just over 6 months sober. I was the oldest one in my treatment program which probably averaged 30 years old. One thing I note; you don't see too many old 'practicing' alcoholics as they usually die premature. On the other hand I've met numerous very old recovering alcoholics many older than I. At our age there is no 'future' in drinking. The great alcoholics die young.
