You had a great run my friend
Daltrey contracted viral meningitis a few years ago and thought he was going to die. That’s a disease that can do nerve damage and harm hearing and vision.
Once we recover from an infection we tend to think that we go back to how we were prior to getting infected, when in fact it may leave a calling card behind. Old age may in part be the collective slings and arrows from all of the illnesses we deal with over the years.
