Me: I have this new character. Her name is Invincigirl. She’s invincible to everything. She can’t be crushed, suffocated, starved, etc.
Kristin: Can she break bones?
Kristin: Can she bleed?
Kristin: Can she age?
Me: Um, I haven’t thought of that.
Kristin: Maybe she ages slower than normal. I mean, what if she gets osteoporosis?
Me: I think you’re the only person who would consider osteoporosis in a superhero origin.
