From a time before the virus

So you don't forget what it was like.

Before the virus and AFTER polio. I realized the other day that my parents kept us confined a lot during the days of polio before the vaccine. I was forever escaping over the 6' fence, not understanding what was going on.
It's been a long time since the days of polio. Soon, I hope the same can be said of COVID.

If you had polio and survived,it would come back to haunt you when you were elderly, with other symptoms.

A major problem confronting millions of polio survivors is that too few doctors, in both industrial and developing countries, recognize this slow moving and little understood secondary illness, called post-polio syndrome (PPS). The main symptoms of PPS are new progressive muscle weakness that gradually worsens, together with severe fatigue and pain in muscles and joints. It is often accompanied by decreased muscle endurance during activities.
