My siblings, cousins and I, like our parents started drinking our morning coffee with our parents as teenagers, and they did with their parents.
No cancers yet and most of us made it into our 80’s or close to it including our parents and grandparents.
No telling how many car/vehicle accidents were avoided by having a cup of coffee when needed before driving or during a needed coffee break while driving.
When I was a little bitty toddler, I’d get up early with grandpa and we’d have coffee together. His was straight black (lived into his 90s and no cancer). Mine was 99% milk. Good memories.
