I agree. It’s also probably person to person thing.
I’ve been told it’s better to take ibuprofen with food as you can get indigestion. But I don’t so I don’t need to. Some people need to. Some people get indigestion so bad they can’t take ibuprofen at all even with food.
Also I went to the doctors and he said “just take some ibuprofen that will help” and I said “oh I’m asthmatic I’m not meant to take that. But I have taken it before and I didn’t realise”
And he said “oh its fine then. Some asthmatics might get any issue with it. That’s why it’s recommend not to take it. BUT seeing as you have and didn’t have any issues, then you are fine to take it.”
There is a huge theoretical improvement in medicine if it can be given individually rather than by demographic.
