I'm not surprised in some ways - I weeded for 2 hours at allotment, then a bit of work in back garden. Half an hour yoga and 8 minutes jogging on the spot. I feel ready for bed now, and I know I have exercised, but I could do this and much more not that long ago (January).
I am lucky that I can do so much, but I hate feeling so tired, so early.
