So how long do I have? Also, if you guys could hurry with the answer...?

    I can't really find a good number for how cold you can get and not die, so let's say 20 degrees. That gives 16 degrees to lose.

    Meat has a specific heat of about 3.5kJ per kilo per degree, so say you weigh 70kg, that's about 4 million joules to lose before you die.

    At 650 joules per second, you've got slightly over 10 minutes. Of course, shivering will burn more calories and stuff, and the panic of impending death will likely stretch it a few more.

    I didn't include clothes, because then the maths would make me cry.

    4,000,000/650/60=102.57 minutes

    But that's for a resting body, a shivering one would lose only like 200j/s

    Also, you forgot one important aspect, if you're getting bathed by the sun and spinning, you're constantly getting heated up.
