Fit for Survival?

As individuals and as a species we don't seem fit. Perhaps we've arrived at our evolutionary dead end, but who knows, our species is very adaptable. Now as individuals, we all know we'll reach an end point. To my mind, the question is with what quality of life. My partner often asks, "Why are we so lucky?". There has been some luck and tricks of fate, but some of our quality of life is due to planning...doing without so that now we have enough to be comfortable. We also had the foresight to buy property when it was fairly inexpensive. Taking care of our health has paid dividends... we have no big medical issues. Others in the US are not so fortunate. The health of so many is poor and is one reason US COVID outcomes have been the world's worse. Now, we can go forward making better choices as individuals. I wish we could do the same for the society, but so many road blocks impede real progress. So are we fit to survive? Will we evolve?
