Doing the math

Woke up late one day and while having breakfast i wonder how many days does a man spend sleeping considering he’ll live for seventy years and has regular eight hours sleep daily?

this is my attempt to compute (haha!)

Now let’s compute how many hours does a man sleeps in a year considering he has regular 8 hours sleep daily:

Now let’s multiply that for seventy years and we’ll have:

So if a man lives for 25,000 days minus 8,540 sleeping days he will have 17,010 waking days, that is 47 years only! 😯

Cool! So what’s the lesson here? Math is fun. Mathematicians are wise people according to Proverbs 90:12

Teach us to number our days aright, that we may gain a heart of wisdom.

current mood: all these math makes me want to sleep.
