       The average red bloods cell lives for 120 days. There are 2.5 trillion [  give or take ] of red blood cells in your body at any moment . To maintain this
number   , about two and a half million new ones need to be produced every second by your bone marrow. That's like a new population of the city of Toronto every second.

   Highest Point on Earth Is Not Mount Everest

       True, it's one of the most famous mountains in the world , and at 29,035 ft. above sea level it's pretty darn tall. However, considering we now know that the Earth is not round, anyone or anything along the equator is slightly closer to the stars. this means that although Mount Chimborazo in Ecuador is just 20,564 ft. above sea level, because it is on this " bump" it is technically further away from the Earth's centre [ i.e. " higher" ] than Everest by 1.5 miles.
