The term “life starts at 40” was coined by a man called Walter Pitkin in 1932.
That is much truer now than it was in Pitkin’s day, thanks to advancements in medicine and a better understanding of health and nutrition. Still, reaching 40 is a significant milestone. If nothing else, it’s an occasion to honor someone special in your life.
