Not really. You can't, for example, lift weights 8 or 12 hours a day unless you're taking steroids because your muscles need to heal and they can only do that between bouts. You can through-hike long backpacking trails but it takes a toll on your body and eventually you will have to rest. And you can't hike all day and into the night, you need to rest between bouts, again because your body needs to heal.

I think the dangerous thing about people thinking you have to code all the time is that they're just assuming that it makes you a better coder without any real reasoning. And that's the kind of assumption that is very prone to confirmation bias.
