I'm so sorry you fell, Bobby!
I'm so happy you didn't hurt yourself tho! I have also been lucky about not falling lately, and not hurting myself either (knock on wood).

I remember you bought a regular exercise bike vs. a recumbent one (close to the ground with a seat that has a back)...
So, I agree 100% with Donna. Don't use the bike while you are alone. It's not safe. And Marci is there to clean, not to be an attendant or personal caregiver, so it's not her job to spot you. Can't believe the PT would suggest otherwise...

How is the new book?
