Anecdotally, the only people I know in the UK who wear fitbits these days are retirees.

I have seen a huge increase in the number of people out and about running. Perhaps they all ran on treadmills at the gym before (we are permitted to leave the house once a day for a run/walk/cycle), but from my anecdata I've seen perhaps a 5x to 10x increase in other runners out when I am running in London so a drop in activity does not tally with my personal and limited observations.

It would not surprise me one jot to see that retirees (i.e. those most vulnerable to corvid) are not out and moving around as much.

I've noticed far more people running where I live in the U.S., too. Today, it was cold and raining, and runners were everywhere. Ordinarily, I'd have expected to be the only one.
