10 hours, but I’m also a fatty.
Back in college, my buds & I did a road trip across America, so of course we stopped at the Grand Canyon. Breakfast was just a peanut butter & bread “sandwich”, at which point we started hiking down the canyon. If you’ve ever been, they have numerous signs saying “Do not go past this point unless you are packing food”. But hey, we’re college kids, and we’re not going to go THAT much farther… Long story short, that night the rangers had to chaperone us as we fucking crawled back out. One of us ‘got’ to ride in a helicopter to the medical building. For the other 3 of us who could still move, they manged to find a dusty MRE at the last way station. That was the absolute best chicken & pea soup in a tin foil bag I have ever eaten in my life.
I was just thinking this morning that it’s kinda odd that there’s no cell phone that also doubles as a multi-meter for measuring electronic current. I guess it’s because in theory you’d need to also carry around a set of probes with you?
