This is also varied heavily in the US? My wife and I joke all the time that the 70yos are out jogging every day where we live, now. There is a set of cyclists that are all in their 60s we see several times a week outside of our house.
Just writing that, though, makes me realize that most of the northern sections of the US are inline with what we call western Europe? Would be neat to see this broken down by latitude as a crude cohort check.
A lot of Europe experiences longer days than PNW during spring to summer.
