Hello Debbie,
Being an introvert in a extrovert job required learning skills to overcome it. Can you believe I have a Masters Degree in Counseling Psychology? I was considering changing careers from law enforcement to psychology (have B.A. degree is criminal justice also) but found the psychology training helped me be a better employee, friend and husband to those around me.

Water aerobics worked for me. But just find something you like to and enjoy with those around you. It does wonders for your mental health. I can't stand my signing voice. But all of us are singing and no one knows who's voices you are hearning.

It is just so much fun I don't even think I am exercising. Met a lot of friends this way and you can tell I encourage others to find an exercise or hobby you like doing and do it. Now I love doing water aerobics with my friends and fellow exercisers but I also love to bike but alone. I want to look around, stop and walk and just find the peace and quiet of it just so relaxing.

I have an ICD/Pacemaker and never worry about it. Just to let you know many in water aerobics are handicapped. The water helps support them and are able to exercise in the water where they would not be able to do ouside the water. On some days I do back to back classes.

You mentioned life preserver what some wear is a float belt. Not for life saving but helps keep weight off their legs as many have bad knees, hips, etc. Again water aerobics is what you put into it. You can use very light weights or very heavy ones. Work hard or easy. Of course how you benefit from the water is the resistance you get from moving IN the water. You always see films about participans with arms out of water. That is not how they are taught. You use the resistance of the water to make exercising harder.
Take care Debbie!
