Over 50 About how much caffeine do you use daily?

I am 56 and I need 150mg a day. I try to use less and I struggle to finish 30 minutes of disc golf by myself.

Also my brain does not function as well.

My grandparents all drink about 3-5 cups off real coffee per day. I usually do not drink coffee. I also try to keep soft drinks to 1-2 a week.
