Most of the elderly have decreased physical function, osteoporosis and inconvenient legs and feet. Standing on the bus is more prone to danger. It is also a fall injury, and the elderly are more prone to fractures or fractures, and even accidents. Therefore, compared with young people, the elderly are weak and need the care of the strong. Taking care of the weak by the strong shows respect for people. Young people will grow old slowly, and there will be times when they are helpless. Respecting the elderly now is actually respecting yourself in the future.
Giving up one's seat is a state, not an obligation except for the seats reserved for the elderly, the weak, the sick and the disabled. Some young people are in poor health and weak, so they deserve to give up their seats and be taken care of.
Respect is mutual. The old man, like a tank, pushed everyone away with a Machamp, got on the bus first and then let others give her a seat. Such people do not respect others and should not be respected.
