Mercedes team chief Toto Wolff says he has no problem with star driver Lewis Hamilton's passion for extreme sports, despite the injury risk to such a lucrative asset.
Hamilton's adrenaline-fuelled off-season hobbies, including skydiving, surfing, snowboarding and riding motorbikes, have raised eyebrows in the past.

"Of course, I'm always worried and we had a laugh last year because I couldn't get hold of him or my chief strategist or one of the race engineers because they were racing motorbikes," he said recently.
"But Lewis is not an 18-or 19-year-old young man anymore, he is a five-time world champion and he knows exactly what works for him and what doesn't.
