This is how a Formula 1 driver sits for two hours while racing at nearly 300 km/h, tolerating over 5Gs. So yea, go sit like that for an hour or so, see if you are fit enough for your dream job. As Mercedes driver Nico Rosberg explains, you almost lie down in the cockpit, with your legs almost at the same height as your head. Come to think of it, this is the only way you can sit in an F1 car, because of its height and aerodynamic considerations. And this is why successful F1 drivers are usually, well, small.
While you are practicing sitting like Nico, imagine crashing in this position. Still fancy F1? Of course you do! That’s a small price to pay for what you gain in this sport.
