If you are like me and normally end up working more than an 8 hour day on a normal basis then a hot shower at the end of the day is a better way to unwind than a beer or a tumbler full of bourbon. At least in my opinion anyway. Honestly just the feeling of being clean is an energy and moral booster in general. However, if you happen to be fortunate like myself and have a pulsating shower head it provides for a nice massage and combine that with the hot water helps take away the aches and pains of the day.
Even in the event that a hot shower is not an option just washing ones face and hands is normally enough to restore some energy and remove the dirt and grime from the daily grind.
