The 29-year-old has been dogged by injury problems in the past 12 months since rupturing his Achilles against Wales in the 2008 Six Nations tournament.
But Moody has no thoughts of hanging up his boots and even has another World Cup among his potential targets in two years' time.
He said: "I am still pretty fresh in terms of my body even though I've had a number of operations.
"I'm 29, if I get in another four or five seasons, I'll be happy with that. You never know, I might go longer but it might go shorter.
"I am just happy playing rugby again - and I'll be playing it as long as I can.
"The next World Cup is only two and a bit years away now. I'll be just 32 at the start of it. We will see how it goes.
"I'm all about just getting in as many games as I can, whether it is Leicester or England, and hopefully my body stays fit long enough to make that happen."
