How much time do you think we spend, on average, in the shower? To give an idea, the average man in the US spends about 62.4 hours a year in the shower (2.5 days), the average woman in the US, 65.9 (almost 3 full days). Over the 60-ish years of your adult life, you spend about 6 months in the shower. Imagine how much time you’d save if you didn’t shower daily? You might even have time for an extra few minutes of sleep!
