I just wanted to remind you guys how important physical exercise is to our bodies.
I was feeing worse recently, but since I am getting fatter and fatter, I finally decided to move a bit. I bought a stationary bike and I cycle each evening. It's not much, but only after a couple of days I feel better. I have more energy and am more enthusiastic. The endorphins are working, believe me.
So start moving, if you can. Don't overdo, you need to see small progress and satisfaction, not exhaustion and fractures.
