Maybe they have evolved over the 20 years, as I was not given any of those restrictions. They were more worried about dust and hay. I was back in the saddle 5 months after transplant. I could not have given up my horses (or dogs). They aided in my recovery immensely-whether it was riding or walking my dogs to get my strength and stamina back and to feel like the old me.
I had a congenital heart issue with related pulmonary hypertension that caused the need for the heart-double lung transplant.
