Yesterday I advised somebody that physical activity is highly beneficial for mental health and can help more than medications would alone. The community did not like that. I am here again to remind you that physical activity is Paramount to mental well-being. Go out and garden. Take a walk in the park. Go for a jog, whatever it may be that gets you out of your current location and allows you to reflect and think.

Great to hear that you found something that is working for you!
But not everyone has the same issues as you. For some it might be even contraproductive to reflect even more, because its their issue that they do it already too much
While it’s helpful (and important for most people) to ALSO do physical activity, many (most?) people still need their medication.
I have never in my life told a single person to not take their meds.
Airbags will prevent more injuries in automobile accidents than seat belts will alone. This does not mean you shouldn’t wear your seat belts. It means you should wear your seat belt and have a working airbag.
I like your metaphor, i think it’s fitting very good :)
But the rest of your statement: i read your comments to Canconda in this way. I seems to me that you at least you are implying it.
Revisiting the metaphor: Canconda. Would be a person who has removed their airbag. Who is saying that actually they had a bad experience with an airbag once so it’s not for them, and actually airbags don’t work and are stupid. Nobody should use an airbag seat belts are fine and that’s all you need.
I’m shocked you’re being upvoted when you’ve basically just put words in OP’s mouth. They didn’t say anything about not taking medication.
Your point about “it might even be harmful for some people” makes about as much sense as not recommending leafy greens because some people might be allergic to them.
Reading comprehension on the internet. How dare you!
