I think that's I think it's an important metric that again I I just don't see a lot of attention to because I think if people could experience the increase in energy that is the consequence of working out at the right intensity in the right way at the right times for them they'd be much more apt to do it it wouldn't feel like this like spending money on something that sure will make you live longer but then you're depleted and you can't do cognitive work
