Some of the best / most nuanced medical advice I've ever received is from online forums.
I think what you really mean is "don't risk your life on the basis of advice from strangers".
Note that all the other answers ITT say "yes anything that elevates your HR is dangerous", so OP knows not to play that type of game before his next appointment with his cardiologist, which could be weeks or months away.
Had they not asked, they wouldn't know to avoid that activity.
There's nothing wrong with Lemmy growing in an organic sustainable way, but I dislike the attitude that lemmy ought to be a reddit replacement or that lemmy should grow from the ashes of reddit.
Lemmy should be it's own thing with it's own culture and history and communities.
I get a bit peeved when lemmy users (not necessarily you) get a bit obsessive about transferring communities to lemmy from reddit. Just focus on creating good content for Lemmy and forget about the rest.
Imagine around the advent of readily available photo prints. People might have been thinking "this is terrible, someone I don't know could have a photo of me and look at it while thinking licentious thoughts!"
Baseless assumptions.
