Toilet

A person generally take 6-8 min to go washroom in a whole day [ accept mobile users who take the phone to toilet] so , we will take 8 min [ because it includes every thing] so , let's calculate.

1 week - 7days multiple by 8 min = 56

1month[30days]-8mins multiple by 30days = 240mins or 4 hours

1 year = 365 days multiple by 8 mins =2920 mins or48 hours or 2 days [0.54 percent of year]

Average human being - 65 years multiple by 2920 mins = 189800 mins or 3164 hours or 131 days or 4 months or [ 0.5128 percent of life ]
