I really enjoyed the snippet. I worked with the elderly for a significant percentage of my working life, about 25 years. I sometimes wonder if it isn't harder to be a person whose mind is still all there but whose body is betraying them.
Taking it slow after a heart attack is the right thing to do.
I'm still working on editing The Wizard's Key. Which I totally didn't finish two years ago. Nope, I just finished it yesterday! I promise. ;-)
