This 101 year old lived through a world war with rationing, would have been born into the great depression, saw the rise and fall of Nazi Germany, the Cold War and Cuban Missile Crisis, the Kennedy Assassination, the Nixon years, the oil crises and recessions, Gulf wars, 9/11...
On the healthcare front there was the proliferation of lead (in paint, toys, fuel, everything), smog from cars and coal burning, toxic fertilizers, the rise and fall of smoking, the discovery of HIV, Polio outbreaks, things like the Cuyahoga river fire (where rivers were so polluted they literally caught fire every couple decades). The mining town my family lived in would just throw the arsenic and mine tailings into the lakes because they figured it couldn't hurt them there, and that was a common thing to do at that time.
Gen X and Millennials are not the only generations who have faced adversity. It's a rough moment now for sure, but it's not unique. We shouldn't fall into baseless optimism but also don't shouldn't neglect human strength and creativity. We have new problems, and we have new tools.
