I have a neigbor that cannot breath after shoveling some snow. He is 65, has not been to a doctor in years. I. Say ch, but there is no chest pain.?

Get him evaluated. If he is a friend, he might let you take him in to the physician to get checked.... Some people hate to go to the doctor alone. The sooner he is seen, the better. There are many things that make you breathless after exercise, so get him seen and get to the heart of it.
Several. Different problems could be causing his breathlessness. Could be congestive heart failure or chronic obstructive pulmonary disease. Severe deconditioning could also cause this. Most causes would be treatable. Urge your neighbor to see a doctor.
