It's not unnatural!!!!!!!!!!!!! Snakes suck. My Dad is the spookiest snake hopper Man known on the east coast. He's all man, in fact now at 70 he still looks better than 95% of the guys I see. But snakes will test every reflex in his body. He is like a cheetah when he sees a snake and even when he thinks he sees a snake. My Grandmother his Mother was the same and even though when young I would grab a black snake and wrap it around my waist in my youth, later I would see a silly piece of hose and if it even looked like a snake I'd jump. I have never had a bad experience with a snake.
This is the best I can tell you. Buy him the best snake gear you can buy. It won't matter he won't get bit. You will right behind him, after he leaps up out of the way. LOL! I'm serious. You should see my dad hop.
He has some heart tests Friday, think of us.
