How would your life be different if you were incapable of feeling fear? Would your life be better or worse than it is now?
Not to be a smart ass of anything, but I’m pretty sure I’d be dead. Dead because of that time I walked onto a busy freeway without looking, or jumped out of that airplane without a parachute, or let that ax-wielding serial killer into my house. No fear = death. That’s why it’s part of our dna. Survival.
