  • The global life expectancy is 71.4 years.

  • But in the US it's a bit higher at 78.6.

  • This amounts to 28,689 days or 2,478,700,000 seconds alive on Earth.

  • So what can happen to you in that time?

  • You produce 0.4 millilitres of saliva per minute and 0.5 - 1 liter per day.

  • That means in a life time you can fill anywhere between 180 to 360 bath tubs full of spit.

  • Men cry an average of 1 time per month and women 2.7 times, giving you an average of 1,745 good cries per lifetime.

  • The average adult is not getting their 10,000 steps in as the average US adult only takes around 5,100 steps per day.

  • From the ages 20 to 60, it's estimated to learn 1 to 2 new words per day with an average total of 42 thousand words.

  • This number declines as we age and is likely related to our brain decaying at a rate of 5% per decade after the age of 40.

  • The average person 15 years or older in the US works 7.9 hours per day.

  • And with the average age of retirement being 63, you'll spend about 16 years in total at the office.

  • But are you really working or just looking at memes?

  • One study found that young adults use their phones 5 hours per day and check their phone in 30 second burst 85 times a day.

  • When you do the maths that adds up to almost 13 years on your phone.

  • By the age of 30 you'll likely get the flu twice every decade.

  • The incidence may decrease as medicine continues to improve but may also increase because of the amount of time we spend indoors.
