The Art of sitting
There have been many comments regarding the dangers of sitting, along the lines of "sitting is the new smoking." Do you think there is a more nuanced possible perspective?

Just like with standing are there in your view harmfull and healthy forms of sitting?
To gain muscle, a one-off steroid cycle
Thought experiment only: What if, at age 55, a person were to do a cycle of steroids for the purpose of building as much muscle as possible, so as to help with long term strength?

(Also, I’m older than 55 and don’t think the pros outweigh the cons for me.)

Can I still maintain cardiovascular fitness with such a lower threshold of exercise capacity?
