Also the more healthy change from a scientific point of view.

Ironically the parent post seem to be a person with a social yet lack (i.e. forced to stand up earlier then their inner clock, i.e. often stands up late). But especially people like that are biologically negatively affected by permanent summer time.

Off topic, but what is your native language? Your use of "stand up" suggests German, but "yet lack" sounds vaguely... Scandinavian?

It's German and it's a Typo, maybe autocorrect.

I meant Jet Lag, which is also used in German as Jetlag.

But I somehow thought it's written Jet Lack and typoed it as yet lack. No idea why I thought it's Lack, maybe because you lack sleep after taking a jet ?
