I seem to be more pessimistic in this regard.
Too many diseases that were gone, now returning.

Too many skipping vaccinations and spreading diseases.
Too many (new) Drug resistant
Super bugs/viruses ( stop taking all those Antibiotics people )
Too many “new” Xtra Potent drugs..pot I’m looking at you, that is already causing an increase in addiction related issues.
( and no I’m not talking about medical grade)
Way too many Suffering and Dying from various diseases that Still

have no
Cure...despite $$$$$ and hardworking researchers

And some other reasons.
Optimistically... I’d love to believe that people are more in tune with their bodies and taking better care of them.
That Cures are just around the corner!!!
I agree ... we re living longer than years back.. and I HOPE it continues to improve
( quality wise)
