I'm 51. I drank beer in high school/college, then stopped for decades. Ten years ago I started to enjoy a craft beer with a meal and/or a movie. Now I have a couple after a ride with my bike team, and a couple with a movie. Some weeks I don't drink anything, some weeks I might have 5 beers total.
If I drink too much it makes it hard to ride a bike, drive a car, stand up, etc., so I don't drink that much.
I don't get hung over. My body seems to metabolize alcohol better now than it did when I was young.
I don't have trouble sleeping, but I don't drink right before bed.
