Richard LittlerI do exercise to keep thing ticking over. 5km jogs. You hear of people who experience feelings of well-being, even rushes of euphoria, to which they become addicted. Who *are* these people? Sport/exercise to me has always felt like being dragged around a field by a rabid bull. A necessary evil.

@Richard_Littler not sure if real high euphoria... But in 2019, when I started running regularly (~4 km/day in quiet local forest) it was the first time since secendary school when I didn't feel that constant background sadness. Well, few months without depressive mood as normal baseline of life... It was kind of surreal itself.
