Ask A Leech: How Do You Survive A 24-Hour Submersion In Liquid Nitrogen?

How much cold can you withstand?

In August 2010 the coldest temperature ever recorded on Earth was measured in Antarctica; it was a staggering -94.7 ⁰C (though it was not an official record because it was measured by a satellite).

Yes, climb trees.
