Here is the data on prescription drug use by age bracket.

18-29 years: ~30-35%

30-39 years: ~40-45%

40-49 years: ~55-60%

50-59 years: ~70-75%

60-69 years: ~80-85%

70+ years: ~90-95%

You can use those numbers as a lower bound of "health level warrants medicating" since many can't or won't get medical care.

So Congrats! You have now entered the top X% of health for someone your age. Well Done!
