This automatic assumption that one will be always "sick" when one crosses 50, 60, or whatever and , and will need medication ... Where does that come from?
The "modern" medical system has effectively ensured that.
Medicines are meant to be taken when you are not well. Being "not well" is not a continuous condition.
The human body is designed in such a way that we will always be well. There will be brief periods of illness when we need to pull back on activities, give the body some rest, maybe take some medicines, and allow it to recover. This is irrespective of age.
The default condition for the human body is wellness, not illness. Modern lifestyles, food lobbies, and Pharma mafias have ensured that the reverse is the case
