Yes, I think elderly people should definitely teach young people how to fix things. They have a lot of experience and skills that are really valuable. By sharing their knowledge, they help preserve traditional techniques that might otherwise be lost. Plus, it creates a bond between generations and teaches young people practical skills that are useful in everyday life. It's a great way to encourage problem-solving and self-reliance.

I don't think it's necessary for elderly people to teach young people how to fix things. Nowadays, young people often prefer learning from online tutorials, which are more aligned with modern technology. The skills required today are different from those in the past, and older people might not be familiar with new tools and techniques. Additionally, young people might not have the patience to learn from older generations, as their interests and priorities can be quite different.
