Today's the first time since recovery that I went downstairs to take a walk after dinner.
After the first round (about 0.5km), I started to feel short of breath and my knees mushy. I was appalled because I used to do about 5 rounds way "back then".
I even considered if I should gone for physiotherapy. But anyway, I pushed on to a second round and oddly enough, it seems that after that hump, things eased.
I could have gone another round but I didn't want to push too much for a first day.
