About a week ago, I had decided to quit drinking cold turkey and although it didn't last very long (I started drinking again after about a week) I found that physical activity such as going to the gym helped me tremendously. I have always been a natural athlete and very passionate about sports especially soccer. I stopped playing for long time and being active , and soon my entire world become engulfed by my addiction. After working out last week, I really noticed a particular change in my attitude. Although I was tired and exhausted from working out, I was very happy and noticed that I was smiling more often. I have always wondered about physical activity and how it can affect ones happiness which doesn't really surprise me that I was feeling great after a workout like I had when I was a younger athlete. Has anyone else found that their attitude changed for the better after being more physically active?
