Exactly. As someone who wants to be a conservation officer, this especially applies since conservation law enforcement involves hours of patrol on foot, going up and down mountains as well as search and rescue, first aid and so on. I've watched game warden shows on the nature channels and it is not at all uncommon for them to actively chase poaching suspects on foot or even carry an injured hiker down a high mountain. You also don't have backup alot of the time, or any is far away. But if the current obesity trends mean anything, I'd pretty much be on my own.
