Earlier quoted context omitted.
I had Delta once. Prior to it I would ride 30 miles on my bike like it was a breezy day. When I'd take breaks to vacation or whatever I could pick back up easily. A year after COVID, I'm struggling to hit 20 miles and I lose my progress easily. I'm not sure it's COVID related, but nothing else has changed in my life.
Lockdowns have also broken everyone’s regular exercise and healthy habits. On charts we all assign this to Covid, but lockdowns were an artificial, additional decision.
And before you come out with the usual "you just need to use more imagination and take your kids with you" - for a start, the situation I described above drained more energy and life than I care to remember. Also, there's only so much a 1 year old will put up with, when I am used to rides of up to 100 miles.
Personally, I am deeply embittered by the whole experience.
