It's all relative.

I had a patient tell me this morning, "Hey I'm a healthy guy. Honest, I'm really healthy.
Me: "Um sir, you were discharged from the hospital last Thursday after a six vessel coronary bypass."
Patient: "I know and I feel great."

When I asked him if he used a walker before the surgery he responded with "Hell no. What do you think I am? Some old man?"

I could use seeing more patients like this.
