Respecting elders is important because they have more experience than younger people and are able to share their wisdom with others. The elderly need support, and teaching respect makes young people more likely to help. Respect for the elderly is common in many cultures.
Throughout the world, young people are taught to respect older people. Part of this has to do with how much the elderly can help the younger generation, and it is often people who are too old to work who teach valuable lessons to the younger generation. When formal education was rare, the elderly would often serve as the primary teachers of younger generations.
Respecting the elderly is also a sign of compassion, a trait that many cultures value. The elderly often need assistance and cannot provide the same benefits to cultures as younger people. However, humans are social beings, and they care for those who need assistance. Respecting the older generation is about manners, but it is also about ensuring that they are taken care of by society.
Respect for the elderly is common throughout the world, and many believe it is a natural human impulse that has become enshrined in collective wisdom. While different cultures have different ways of showing respect, it is nearly ubiquitous in ancient cultures.
