My granddad smoked all his life. When he was 65, he had only 20 % of normal lung capacity left. Walking was like running a marathon for him. He could not even stand up straight more than a few seconds at a time without getting short breath! His slow death in a hospital bed at 71 was a drawn-out struggle for oxygen. He had tubes up his nose, but was choking for lack of oxygen anyway. Just lying there was more than his body could handle.

Have fun wasting your body!
