Experienced England fast bowler Darren Gough has pledged to keep playing as long as he is physically able to do so.

Gough, 34, is with the England squad in Namibia to prepare for one-day tours of Zimbabwe and South Africa.

"I've hired a personal trainer for the first time, and I've seen the advantages of that and learned new things," Gough told reporters on Thursday.

"I'll do anything to play for England, and as long as I'm fit and I think I can do a job I'll still play."

The dressing room atmosphere under captain Michael Vaughan is another motivating factor for Gough.

"I'm enjoying my cricket more than ever," Gough said. "I'm enjoying being in an England team that's together, not a collection of individuals."

The Yorkshireman railed against what he sees as prejudice against older players.

"I'm 34, and (Australians) Damien Martyn and Justin Langer are the same age and they're still playing," Gough said. "Darren Lehmann and Glenn McGrath are older than me.

"You can say Gough won't make the (2007) World Cup squad, but half of this squad might not be there either."

Gough said he and the squad had come to terms with playing five One-Day Internationals in politically troubled Zimbabwe, starting on November 26 in Harare.

"We talk about the odd thing, but we don't sit down and discuss it," he said. "I thought about it long and hard, and in the end I came to play cricket.

"If I didn't go, somebody else would have had to. It's as simple as that."

England play warm-up matches against Namibia on Sunday and Tuesday, but rain every day since the squad arrived in Windhoek has hampered their preparation.

Thursday's middle practice was cut short by a thunderstorm, and England are scheduled to make another attempt at their first full scale outdoor training session on Friday afternoon.
