Its totally irresponsible for a newspaper to run this story. This guy put himself in more danger than the rattlesnake bite did. He needs to find a new doctor - bloodletting is so 1875. Modern medicine has dispel these old theories as doing more harm than good.
For anyone else reading this:
If you get bit by a rattlesnake or copperhead on the park, don't panic, dont start stabbing yourself and trying to bleed as much as possible. Just get your stuff together, leave immediately and get medical attention.
