James Anderson says he has no plans to retire and is feeling as good as ever ahead of a vital summer.
England is hosting this year's World Cup in which the 36-year-old Anderson will not be involved but he will be back for the Ashes which follows it and he says the decision to not take part in limited overs cricket has boosted his longevity in the Test arena.
He said: "With me not playing one-day cricket over the last few years, it gives me that extra time to work on my fitness and stay fresh. I never really look too far ahead but I have no plans to finish up anytime soon.
"I will take it series by series and see what happens."

Anderson is now the fourth highest Test wicket-taker of all time with only three spinners ahead of him in Muttiah Muralitharan, Shane Warne and Anil Kumble.
He took 10 wickets in the recent series against the West Indies which ended in disappointment for the team in contrast to their success in Sri Lanka and Anderson says the Test side will have to adapt better to the conditions if they are to regain the Ashes on home turf.
He said of the lessons to be learned from defeat in the Caribbean: "It shows that when we have a clear idea we do well but when we had to adapt we weren't quick enough to pick things up and that is something we have to improve, even in English conditions.
"The five grounds we play the Ashes on will all be different and whichever team adapts best to that will come out on top. That is something we have to improve."
