What's wrong with old people walking with strong legs and no roots?

This situation is generally due to cardiovascular diseases such as lumbar spondylosis, leg joint degeneration, hypertension, and symptoms of poor blood flow in lower limbs or dizziness and fatigue when walking caused by calcium deficiency.

It is recommended that the elderly keep exercising. You can't be strong without exercising your muscles. It is beneficial to go out for a walk often. Usually pay attention to supplement protein and various vitamins and minerals, eat more beans, eat some meat and eggs in moderation, and eat more fruits and vegetables. It is also possible that the serious loss of calcium leads to stuffy legs, so drink more milk and other things to supplement calcium.
