I find this very interesting, I have no advice but simply my opinion on snake bites and my experience.
I've taken a few bites from my 100+ lb german shepherd / rotty mix (unintentionally) as him and my other dog sometimes get too rough playing and I have to separate them and those bites hurt and do a lot more damage than a ball python ever could but it doesn't scare me off of letting my dogs sleep in my bed or play with me.
We are naturally scared of what we don't know and with public perception of " the big bad snakes" we associate them with danger and don't take the time to get to know the animals and understand them like we do with dogs, creating a fear of them.
Ball pythons don't hurt when they bite but the thought of being bit by a snake is intimidating and I feel like it comes from the overall perception of snakes being dangerous and bad. Of course no one on this site believes that but, personally, I think it goes back to your natural instinct and what you were taught of snakes being dangerous.
When I was living with my parents they wouldn't allow me to have snakes and they were terrified of them so I didn't handle a snake until I was 17 and living on my own.
For 17 years I was taught that snakes were bad, leave them alone, and now sometimes when I see one of my snakes (who I know is friendly) coiled up or looking defensive I start to get nervous about being bit and I think subconsciously its your brain telling you what its been told for years: Snakes = Danger
I just picked up a large adult female bp (largest snake Ive ever handled) and seeing how big she is does make me nervous to get bit but as Dakski said, its the anticipation of being bit which can lead you to be more timid and more likely to get bit, the bit itself isn't so bad.
I'm very excited to start handling her once she's settled in, despite my intimidation, because is anything fun if it doesn't get your heart racing?
All in all, don't be worried to get bit, it might happen, it might not, you're not gonna die or even be hurt. Try to get to know and understand your snakes body language and signs of when its scared or defensive because its not biting out of aggression,
your snake is really sizing you up and planning an elaborate jail break to devour you and your family in your sleep.
Or at least that's what they want us to think
