No means a sportsman

I am by no means a sportsman, nor do I have any talent for athletic stuff. However, recently, I do feel that I suffer some kind of syndromes when I absent myself from some kind of exercise. Be it the evening jog, or the afternoon swim. For the past 3 days, I am devoid of physical training (either by weather, work or timing), and I find my mood kind of dull, I feel wasted, or rather I hope to waste some energy somehow. Today evening, the weather is great and I went for my farm mart route. Not a long trip, but a satisfying one nonetheless. I feel my endorphin waking up and I actually feel livelier, and i began to think of what I would like to do tomorrow.
