There would be a way to calculate the ratio if you look at the world population chart
Im guessing its somewhere for every 1 that dies 1.3 are born or something seeing as the population has been increasing
But that ratio is going to be constantly changing because of longevity changes
I really like your quote: As lean muscle and functionality become the new gym mantras, hypertrophied He-Men with grapefruit biceps and blister-pack abs have come to resemble specimens from a diorama of A Vanished World. I like the good sense of humor in it!
