Let’s say you are a man and you are quite skilled with the knife, so you need only 2 minutes to shave yourself. If you shave every day this means you will spend 728 minutes per year shaving (you skipped new year’s day). If you shave just once a week, you will be shaving about 104 minutes each year.
So compared to shaving daily, shaving weekly saves you more than 10 hours (actually 624 minutes) … EACH YEAR. That’s over 500 hours (more than 20 entire days) in a life time!!!!
