I feel kinda lucky. Kennedy was president when I was born and I saw the technology revolution. And I've had (and continue to have) amazing times in my life.
The reason I feel I'm lucky at 51 is that I think my body will expire around the time the planet finally starts expelling us in earnest.
Summers will regularly be in the 120's, the air will be virtually unbreathable and the water will be almost undrinkable. Populations will become even more unsustainable than now and we'll start dying off.
If things continue the way they're going...
