Even at 42, Ronnie O'Sullivan's status as snooker's main attraction shows sparse indication of waning. Despite a Saturday which he called "embarrassing" at the Crucible - he trailed Stephen Maguire 6-3 going into yesterday's session in Sheffield - O'Sullivan powered through to win 10-7 and book himself a spot in the second round at the World Championships.
Eating a salad at the post-match press conference, O'Sullivan espoused the benefits of healthy living. His new lifestyle is one he attributes as a factor to his longevity as a force in the game.
"I have changed the way I eat and have a massive amount of energy," O'Sullivan told the BBC.
"Compared to the average Briton, I will always look fit because we are not the most healthy society.
"You go to China, or to the Mediterranean, they eat proper food. It is all pre-packed meals here. You look at the state of some of our humans in the country, they are massively obese. A bit like America."
Follow O'Sullivan on Twitter and you're likely to see him prescribing green tea and running to anyone who asks him for advice. He's actually looking to spread that advice further than social media by co-authoring a health and fitness book - 'Top of Your Game: Eating for the Mind and Body' - with nutritionist Rhiannon Lambert.
"The biggest thing for me this year is how I have eaten and am amazed how good I feel and how healthy I am," said the five-time World Champion.
I want to help so many people who have problems with their weight and want to feel good about themselves. I have been in that situation and there is an answer, you have to seek the right people.
Ever since I was a kid, I have always been on the chubby side, there is a lot of fried food at snooker clubs. Then I got into running.
I feel so good I think I am going to live to 200 now.
