I've been tracking my drinks for 2 years, first time I reach such a sober streak - and I feel really better!
When I was in elementary school, a teacher said like "I haven't had a drink in 5 years" and I said "Wouldn't you, like, die?"
I don't know if he thought I was fucking with him, or my parents told me not drinking booze was lethal, or what, but he didn't like laugh and clarify what he meant.
