Simple solutions to hard problems seem to be falling out of favor.

Actually, exercise lowers cGMP (and low cGMP is what Viagra reverses) so your "simple solution" is actually totally wrong.

Have done regular exercise to improve my Long COVID state for 6 months now. It has helped, but it has its limits too. If I overdo it, I get worse, but I can't always tell until later. And other health issues are limiting what forms of exercise I can do.

Hard problems rarely have one simple solution, or they wouldn't be hard, would they?
