"Although Hoketsu rises early every morning and attacks practice sessions with as much zeal as riders young enough to be his grandchildren, he confesses he does not adhere to the dietary regimen you might expect from an Olympic athlete.
"I eat what I want to eat and drink as much as I want to drink," said Hoketsu through an interpreter. "People might expect that I am able to participate for so long because I have special habits. But my secret is to have a good life, enjoy yourself and do the things that make you happy.
"Having said that, I am out there riding horses every day for several hours. Then I come back in and do many exercises, to help with my strength, coordination, and, most importantly, my balance."
Hoketsu is the oldest Olympian since Swedish shooter Oscar Swahn won bronze at the age of 72 at the 1920 Antwerp Games and would ride into the record books if he was able to qualify for the Rio de Janeiro Games in 2016.
Such an outcome is unlikely, but don’t rule it out just yet.
"My wife would like for this to be my last year of competition and that will probably be the case," Hoketsu said. "But I still feel my riding is improving, little by little. That is my motivation. I am a better rider at 70 than I was at 40. Most people can’t tell but my body is getting a little weaker. My horse knows it and she helps me.""
