A simple math of life !!!!
« on: May 16, 2017, 09:07:59 PM »
1. The average adult, when resting, inhales and exhales about 7 or 8 liters of air per minute.
2. That totals about 11,000 liters of air per day.
3. Inhaled air is about 20-percent oxygen.
4. Human beings take in about 550 liters of pure oxygen per day.
5. A 4 oz or 0.118294 liter pure commercial grade oxygen costs 9.48$ (Boost Oxygen Natural 4 oz. Small Size, Green, Small: Amazon.com)
6. Daily consumed oxygen cost for: (550*9.48)/4 $ = 1303.5$
7. Yearly cost: 1303.5*365 = 4,75,777.5 $
8. Average life expectancy for Bangladeshis: 71.6 (WHO, world heath statistics, 2016)
9. A lifetime cost: 4,75,777.5 $ * 71.6 = 3,40,65,669 $ or 2,74,36,48,981.26 BDT
                           
         

                          TWO BILLION SEVEN HUNDRED FORTY THREE MILLION, SIX HUNDRED-EIGHTY THOUSAND NINE HUNDRED EIGHTY ONE
                                                                        AND TWENTY SIX HUNDREDTHS Taka !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
