As is often the case among the elderly, an episode of fall with broken bone is a double whammy. They dare not move too far. My dad is one of them; he is now more inclined to stay in the Rapunzel-like tower.
The art of aging is to break this downward spiral in the elderly. The less you move, the more likely you are to lose bone density. The same goes for your muscle, which is a lot about "use it or lose it."
The good news about getting old is we have more walking aids nowadays. We bought a sturdy rollator, walking sticks, a quadripod, and a wheelchair. The best kept secret to encourage my dad heading out, I must say, is going to visit him for a walk.
As my dad walked with a rollator with me and my sister this afternoon, ambling in an expression of pure freedom, the joy of stepping out of his comfort zone is all the more precious for being so fleeting. There's no greater wonder than to see my dad smile after going outdoor.
