You must admire his guts (or ego) and determination. Whether it is only as a part of obligation or/and his inner desire to qualify, but we can see that he is still giving his all to try to achieve that despite his limitation which is out of his control. Who can control the time/age? We could say it's his lack of motivation or whatever, but we know that's now what's really stopping or keeping him down all this time. Yet, I still want to see him fight however disgraceful it may seem to some people. I think this dream of playing in Tokyo 2020 is real enough, he probably knows it himself it's not as realistic as it might have been like 3 or 4 years ago. That's why he calls it his dream. I don't know why people have to make fun of it and ridicule him for doing so..
