So I recently got sick and started a new medication to help. I’m suppose to take it every 12 hours, so twice a day. But then other medications you have to take more frequent or less frequent. Meanwhile, food we have to eat on average 3 times a day. But then stuff like vitamins I can take only when I’m sick and be fine. It’s just a weird concept to me that different things we consume have different life spans in our bodies. Overall why is that? Not really looking for specifics on a single type of consumable like food or something. But examples and still appreciated.
