Coffee! I grew up drinking coffee. There was always hot coffee at home. By the time I was a working adult, I was downing 6 cups a day. I think I had more coffee in my veins than blood.
In my 30s, an ice-blended coffee was a good friend on hot days. A delicious treat.
In my 40s, I fell in love with espresso. Or straight up coffee, no sugar or milk.
In my 50s, because of heartburn, I had to stop drinking coffee as much as I liked. I had to limit myself to one coffee a week. That made me sad. I supplemented by drinking tea. I was never a tea drinker, but I've since learned to love ginger tea. Any flavour permutation of tea with ginger/lemon/lemongrass/mint is fine with me.
The best coffee I've ever had was in France. It has been 28 years since, but I still reminisce about the holiday and I vividly recall how I looked forward to waking up in the morning because of breakfast. Freshly brewed coffee in a bowl-sized cup and freshly baked croissant. Simple, and simply satisfying.
