And that there isn’t much one can do to be the same.
I have always been naturally quite lazy, even thought I get on with things like full time work, parenting, try to carve time to be active (failing currently but have been a regular gym goer for years pre DC) etc. But my default is to try and do as little as I can, I love my sofa and love sleeping, would always choose a lie in over anything else. I know some people who have 3 DC (absolute nightmare for me as I feel full on with just 1!), demanding jobs and yet have time to run marathons, be super fit, bike everywhere etc. they just seem to naturally have morw energy and enjoy leading busier lives.
AIBU to think thay you either are like that or you are not? There is no amount of healthy eating and supplements that will get me that level of energy
