My latest obsession has been looking up median ages of countries. It's a whirlwind of a subject and my mind meanders while I write this. I am someone who for all practical purposes is always thinking about metrics, data, conditional probabilities, human behavior, energy, and how they intertwine in stochastic systems. Median age for the last decade wasn't on my mind as much, but now it's going heavily mainstream front and center. Japan will soon have more people over the age of 50 than under which is a bit wild to think about. The median age of the world is ~30 years old. On a 25-50 year basis, my money isn't on India or western countries, my money is on African countries.  Perhaps we all die to a lack of fertile death, soil Salination-Erosion-denitrification...it's hard to say.  50% of the world's 4 quadrillion calories are serviced by nitrogen fertilizer produced with 5% of the world's total natural gas.  That fertilizer wrecks the composition of soil at an atomic level making it less productive on a calorie/hectare basis.  The total debt of the world is about 350 trillion dollars or ~$35k for every man, woman, and child.  Sometimes, I regret studying chemistry and math, but alas...there's only one life to live....well kinda.  Also, I think it's time for some debt jubilees or wars to reset the debt or have it forgotten.
