I highly appreciate that the elderly can still try to learn new things. First, the average life span of humans has been greatly increased when compared with the situation decades ago. It is due to advances in medical technology and the continuous improvement of living standards. So 65 is not the age to die but an age of happy retired life. Second, 65 is a great age when most people can have both time and money, with a relatively healthy body, you can do a lot of things if you want. So it is also a good time to learn something new. Finally, I think it is never too late to learn something new no matter how old we are, because having curiosity about the world is just a life attitude, it is a way to make people feel they are alive and life is meaningful.
