Saw a news story this morning about an athlete, a hockey player, who just died in his early 40s.. obvs way too young to die.. but then i also saw that it said his name and then “1981-2024”…. So what’s making me feel old today is the realization that there are people born in the 1980s who are now in their 40s………. Or, said another way- what’s making me feel old today, and every day, is mathematics .
