Theresa, a retired RN, joined the Y while she was in her 50s, taking classes and exercising. She later began volunteering and then started teaching classes. As one of our instructors, people have said they feel better and stronger by taking her senior classes, and she occasionally hears that doctors have referred patients to her classes. “I have my aches and pains like everyone else. I don’t worry about it. If you sit back and let those things take over, you’ll be in a wheelchair.” Theresa reflected on her own heart troubles by saying, “I survived my heart attack (in 1998 at 70 years old) because I was in such good shape.”
