Endorphins have an incredible hold over the human body. They make you feel good during exercise and some people can't get enough of them - and none more than Michael Schumacher. Two hours after qualifying on Saturday night he was spotted cycling the circuit with his trainer, while other drivers were tucked away in the cool of their team hospitality suites.
Clearly, the heady mix of high pressure, high g-forces and exceptional heat weren't enough for the seven-time champion, and he needed to get his endorphin hit by other means. You're putting us all to shame, Michael. You're 43!
While Schumacher was pounding around the Marina Bay Circuit on his bike, the beautiful people of Singapore were thumping away on the dance floor of the Amber Lounge. Formula One's official party venue is located adjacent to the track this weekend and it's keeping the sport's VIPs entertained until the early hours on Saturday and Sunday nights.
The highlight of Saturday night's 'Lounge' was the Amber Fashion show, in which a lot of the Third Drivers on the grid strutted their stuff in front of a full house. Sebastien Buemi (Red Bull Racing), Sam Bird (MERCEDES AMG PETRONAS), Jules Bianchi (Force India), Jerome d'Ambrosio (Lotus) and Dani Clos (HRT) were the chosen models.
Although there wasn't a winner as such, the cheer for d'Ambrosio was enough to make observers come away in no doubt as to the crowd's favourite. Jerome's blue eyes and dark hair is enough to make any lady melt in this heat, that's for sure!
The Amber Lounge hasn't been the only entertainment laid on by the race organisers over the weekend. The Padang main stage has been packed out with world-famous musicians every night and given that Katy Perry was the headline act on Sunday night, organisers at the Amber Lounge weren't expecting their VIP areas to fill up until after she'd stopped.
However, by far the biggest cheer on Sunday evening was for Professor Sid Watkins. He died last week aged 82 and to celebrate all that he's done for F1 since he came on board as F1's official doctor in 1978, there was a minute's applause on the grid. RIP Sid, you will be sorely missed.
