He's been part of a trio alongside Jeremy Clarkson and Richard Hammond for nearly two decades.

But James May, 56, has admitted that his supercharged lifestyle has taken its tolland the end could be in sight for his part in Amazon's The Grand Tour sooner rather than later.

Earlier this month The Grand Tour’s latest epic journey, in Cambodia, debuted and May et al are contracted for three more 90-minute shows, including one in Madagascar.

'Falling apart': James May, 56, has admitted that his supercharged lifestyle has taken its toll and the end could be in sight for his part in Amazon's The Grand Tour

But May told The Sun that he wants to stop soon because he doesn't want to 'fall apart' in the public glare.

He said: 'How do I feel about ageing? Bad. I'm in the second half of my fifties now and in all honesty, I'm slightly falling apart.

'I'm developing nervous disorders and aches and I don't think I'll do this much longer because I don't want to fall apart in public.

'It would just be a bit undignified and I don't think people want to see it.'

James joked that his co-host Clarkson, 59. whom he started on Top Gear with alongside Richard Hammond, 50, in 2003, will be '60 any minute' and that he 'possibly even more decrepit than me.'

His comments will be dim viewing for fans of the Amazon show as he added that there 'more of it behind us than in front of it' and joked about taking 15 minutes to get out of a Ferrari.

James even told The Sun that the famous trio didn't even think they would be doing the show, which debuted in 2016, for as long as they have done.

The hugely popular show came about after the BBC parted ways with Clarkson in 2015 after a series of high profile bust ups with show bosses.

Clarkson flew into a rage after being told he could not order a sirloin steak after a day of filming in March 2015, calling show producer Oisin Tymon a 'lazy, Irish ****' during a confrontation at a hotel in North Yorkshire.

May and Hammond refused pay bumps and instead moved with Clarkson to start the new show.
