I love to swim and it keeps me in shape

I like it too. It's a good "low-impact" sport compared to running

Yes and I have lung disease its very easy for me to exercise in water, much easier than a gym workout
1_Wizard
That would be a much better activity for someone with lung disease than other recreations, sports, or exercises

Yes and its also low impact on my bones and joints. Older people really benefit from swimming
1_Wizard
It's low-impact because the human body is only slightly less dense than water, which allows the water to support a person's weight

Oh ok that makes a lot of sense and I noticed I do not get as short of breath swimming versus gym workouts

When you swim, he buoyancy  can depend on how much body fat and how salty the water is
