The most important thing is that we remain active as we get older, with aerobic exercise, and also exercises like Tai Chi and yoga, things that improve balance. We want to be physically active in our daily life, and remain active in our heads so we don't feel dependent on other people. Resistance exercise is great for the elderly, as well as balance exercises. Walking activities are important because your heart gets stronger as you continue to practice. Aerobics can even decrease the onset of Alzheimer's so it's working in the brain as well.
