While we have gotten off topic a little, this is something that is IMPORTANT and it is one of the fears I have when the park opens.
When the parks do open, you WILL SEE older people there, people in wheelchairs, overweight people, etc...... Please keep any comments to yourself. It is not your job nor is it any of your business to go up to them and say something. That will just make everything even more hectic than it already will be.
