Thanks for the feedback guys.
He feels fine most of the time. The worst side affect is probably the eyesight, he can read for 10 minutes or so, and his hands are incredibly shaky.
He gets out in the garden quite a bit, mows the lawns, trims the hedge, washes the car, willing to go for a walk anytime, but just will not apply for a job. Maybe he thinks no-one will hire him? His work history before he resigned was brilliant. Hard worker since he left high school, worked 6 days a week, 13 hours a day, would basically do anything at his job, but he now feels as if there is ALOT he cannot do now hes had a transplant. To be fair, he is pretty unfit, hes slim, but will puff out pretty quickly, which is very normal for after all the surgery he has had over the last 2 years. And it wont take that much to get fitter will it?
I am very patient because it's not me in this situation directly. Hes been through so much, so i just basically let him live his own life. I encourage, but not push. It would be unfair of me to keep mentioning it to him. As some of you would know, nobody likes to feel pressured into anything, especially after the transplant.
