What percentage of HOT keepers are actually qualified?

[Praireboyfarmer]

It seems I hear on the News about once a month about somebody being killed because their venomous snake/spider/other exotic animal bit them. Most of the time it is a copperhead (which for some reason, in recent years, has gotten the reputation of being almost harmless)

And recently my Cousin, of who I should say has zero experience with ANY kind of reptile, purchased a Rattlesnake.

Now, I know there are those who go through years of training and preparation and studying before attempting to even tackle the most mellow of hot snakes/other reptiles, but out of the whole of people who own them, how many actually do this?
