Great post! Dogs are a big commitment and as they get older those vet bill get bigger too! I'm glad you're taking good care him, sounds like he's having a few issues. That sagging lower lid is really drying out his poor cornea, that lube should help a lot!
I think you're doing great with your workouts, no pain, no gain unless you injure yourself. I'm glad you have a therapist helping with that part.
