Sleep is one of my favourite activities. This is common after my exit from the full-time employment. I recall the time in which I only slept for about five hours a day during the weekdays in my las job of the full-time employment. I note that having the sufficient sleep is one of the ways towards maintaining a healthy lifestyle. Sleep also makes one feel confident and happy as the fatigue is eliminated during the course of the sleep.
Some people comment that sleep is a waste of time. I do not think so and feel that one will need to sleep well in order to have a fruitful and great life.
