No health concerns for Mercedes' Hamilton ahead of F1 Brazilian GP

After missing a sponsor's event in Brazil on Wednesday due to a fever, Hamilton revealed he was also involved in a prang in Monaco in the early hours of Tuesday morning.

While confirming that his third world title triumph and the days that followed - which included throwing his mum a surprise 60th birthday party - had taken their toll, Hamilton said he had no health concerns ahead of this weekend's Formula 1 Brazilian Grand Prix.

"I feel good. I'm on an up slope, so a lot closer to 100 per cent," he said, having issued a clear "no" when asked if he had sustained any injuries from his crash.

As for the fever, the Mercedes driver added: "I'd gone to Mexico on Wednesday, worked Wednesday to the following Thursday, and then I had my mum's party.

"That was pretty amazing, but I really felt it on Sunday and Monday. Now I'm excited to be here.

"I'm glad there are still two races to go because the end of the season comes and you can't wait to get back in the car, so I'm definitely cherishing the moments I am in the car.

"Otherwise, I'm not as excited for the break as usual. I don't know why.

"I'll be busy, with things I still to plan to do, and I'm looking forward to the training that's for sure because I've definitely put on a bit of weight over the last couple of months."

Suggested to Hamilton his usual intensity had perhaps waned after since securing the title in Austin last month, he replied: "I don't feel like the intensity has changed.

"Nico [Rosberg] is pushing and he doesn't want me to win, I don't want him to win, so that intensity stays the same, so you end up naturally staying in the same zone."

Hamilton had earlier taken to his Instagram account to outline the traffic incident involving his Pagani Zonda.

"I've not been well with a fever, but I also had a road accident in Monaco on Monday night," he wrote.

"Whilst ultimately, it is nobody's business, there are people knowing my position that will try to take advantage of the situation and make a quick buck. NO problem.

"Nobody was hurt, which is the most important thing. But the car was obviously damaged and I made very light contact with a stationary vehicle.

"Talking with the team and my doctor, we decided together that it was best for me to rest at home and leave a day later. But I am feeling better.

"I am informing you because I feel we all must take responsibility for our actions.

"Mistakes happen to us all, but what's important is that we learn from them and grow."
