Why is running bad for me?

　　In my mind’s eye, I’m light and quick as a Navajo on the hunt. That guy on the screen, however,Frankenstein’s monster trying to tango. I bobbing around much, my head was disa(was) ppearingfromthetopoftheframe hong kong fellowship award.Myarmswere(was) slashingbackandfo(so) rth like an ump callinga player safe at the plate, while my size 13s clumped down so heavily it sounded like the video hada bongo backbeat.
　　If that wasn’t bad enough, Dr. Davis then hit slow-mo so we could all settle back and reallyappreciate the way my right foot twisted out, my left knee dipped in, and my back bucked andspasmed so badly that it looked as if someone ought to jam a wallet between my teeth and call forhelp. How the hell was I even moving forward with all that up-down, side-to-side, fish-on-a-hookflopping going on?
　　“Okay,” I said. “So what’s the right way to run?”
　　“That’s the eternal question,” Dr. Davis replied.
　　As for the eternal answer … well, that was tricky Makeup course. I might straighten out my stride and get a littlemore shock absorption if I landed on my fleshy midfoot instead of my bony heel, buuuuut… Imight just be swapping one set of problems for another. Tinkering with a new gait can suddenlyload the heel and Achilles with unaccustomed stress and bring on a fresh batch of injuries.
　　“Running is tough on the legs,” Dr. Davis said. She was so gentle and apologetic, I could tell whatelse she was thinking: “Especially your legs, big fella.”
　　I was right back where I’d started. After months of seeing specialists and searching physiologystudies online, all I’d managed was to get my question flipped around and fired back at me:
　　How come my foot hurts?
　　Because running is bad for you.
　　
　　Because it makes your foot hurt.
　　But why? Antelope don’t get shin splints. Wolves don’t ice-pack their knees. I doubt that 80percent of all wild mustangs are annually disabled with impact injuries Business Centre Mong Kok. It reminded me of aproverb attributed to Roger Bannister, who, while simultaneously studying medicine, working as aclinical researcher, and minting pithy parables, became the first man to break the four-minute mile:
　　“Every morning in Africa, a gazelle wakes up,” Bannister said. “It knows it must outrun the fastestlion or it will be killed. Every morning in Africa, a lion wakes up. It knows it must run faster thanthe slowest gazelle, or it will starve. It doesn’t matter whether you’re a lion or a gazelle— whenthe sun comes up, you’d better be running.”
　　So why should every other mammal on the planet be able to depend on its legs except us? Come tothink of it, how could a guy like Bannister charge out of the lab every day, pound around a hardcinder track in thin leather slippers, and not only get faster, but never get hurt? How come some ofus can be out there running all lionlike and Bannisterish every morning when the sun comes up,while the rest of us need a fistful of ibuprofen before we can put our feet on the floor?
