Could you elaborate on “Toastyour muesli”? What do you mean? Do you put it in a pan?

Yeah. “Calories in calories out” is correct in theory but it is an oversimplification. Most people burn a vastly majority of their calories “at rest” by just maintaining their body temperature.

Just to add to this. Another way could be to find a specific construction. If you could for example find an algorithm that given any even integer returns two primes that add up to it and you showed this algorithm always works. Then that would be a proof of the Goldbach conjecture.

Running. I’m pretty fit and I work out (retty much only bouldering tho). Despite running on average once a month I can run a 45 min 10k. I think if I actually trained for running I could be pretty good but I just prefer climbing as a sport.

This is why grass roots is so important.i struggle to believe in anything that isn’t bottom up motivated.
