Doctors say climbing stairs can lengthen life
expectancy
But doctors at Tan Tock Seng Hospital have found out it
has another benefit. They say climbing two flights of stairs can
lengthen life expectancy by 5.5 seconds.
1 day = 86,400 seconds.
1 flight of stairs = lengthens 2.75s of your life.
You need to climb 31,418 flights of stairs to extend your life
by 24 hours.
Coincidently, to climb that flight of stairs, you probably need
2.75s or more to get from bottom of stairs to top of the
stairs.
Whatever amount of seconds you gained to your lifespan is
negated by those few seconds you used to climb the stairs.
Food for thought.
