Other than this being an anecdote and doesn't mean everyone who drinks heavily will leave to their 90s, the quality of those 90 years matters too!

Though he became Prime Minister for the last time at the young age of 76 in 1951, he was plagued by health problems. He suffered many minor strokes and at least one that left him partially paralyzed for some time. He only stayed on as PM as long as he did because his successor was sick as well (Anthony Eden).

Don't know about you, but I would rather live a healthy 70 years than live 90 years but where the last 20 years are plagued with illness and thus lower quality. In that light, I try to minimize the bad habits that may result in poorer health and thus lower quality life in my later years. Not saying I'm a saint, but I don't need to drink every day or even every week. Currently I'm mostly dry. Saves a lot of money too!
