One of the things that will change is your ability to exercise. Stop and think a moment, your windpipe now has something in it which makes your air intake less due to smaller diameter of windpipe. This means most of us get less air with a trache tube. So try to get the largest diameter trach tube you can get, 10-15mm OD. Now it doesn't mean everyone won't be able to exercise, run, sing, etc. that is person based and depends on why you have a trache etc. Some will be able to do things while others won't. I suggest take things slow, build up your tolerance, and most importantly be patient. There will be many times you just want to throw up your hands and say "I quit." Bottom line do what you can.
