> Context: I'm natively extremely lazy (phisically, not intellectually), I find any phisical activity a pain an a nuisance, I derive zero pleasure from any kind of sport and phyisical exercise (except hiking and skidiving, but not the phisical effort aspects of them), the release-endorphines-on-effort circuit is 100% broken for me or I just lack the receptors for those endophins

It's good to know that I'm not the only one, it's a bit sad to know that there doesn't seem to be anything I can do about it.
