I found myself hooked to youtube so much,I do not why.BUt I like Yotube very much.Daily I create one playlist of my favorite songs and tehn exercise to their tune.It is fairly easy for me to skip my exercise on a daily basis, but it is impossible for me to miss listening my favorite songs.So It helps me in my exercise.Also I am able to do my exercises for a longer duration with these melodious songs.Youtube Rocks!!!!
