It really depends on what needs fixing. If it's something mechanical, the older generation might be better because they have more experience with such things. But when it comes to electronics, younger people might have the edge because they're more familiar with modern technology. Also, it depends on the individual's interest and willingness to learn. Some people, regardless of age, are naturally good at fixing things because they're curious and resourceful.
何を修理する必要があるかによります。もし機械的なものであれば、経験が豊富な年配の世代の方が優れているかもしれません。しかし、電子機器に関しては、現代の技術に詳しい若い世代の方が有利かもしれません。また、個人の興味や学ぶ意欲にもよります。年齢に関係なく、好奇心旺盛で工夫ができる人は自然と修理が得意なものです。
