My wife is using oxygen and I do not think she would do well scrolling, Unless you have superb dust collection or a good mask you can hook oxygen to. If not you are taking in find dust, and you do not want to add any more stuff to your lungs, no matter how fine it is. Sorry you are going though this, it is at best very inconvenient. But it is what it is. I smoked but was able to quit about 30 years ago. She could not. And I think if her lungs healed, which they cannot, she would smoke again... I know she still misses it. She has other problems also and in constant pain. I don't think her pain is related to the smoking. I am 4 years older than her and I am her care giver... My cooking may kill her quicker than anything else. I am not good at it. Thank God for prepared things that I can that I can throw into the micro-wave or oven.. My cooking is so good, I have lost 18 pounds in the past 6 months. Her also. So if you need a diet plan,,, hire me as your cook. You had better like lattice salads.
