Hm. What about something Gem encrusted to high hell that covers our chest and maybe underbelly. (Or just encrusting gems over the wound somehow.)
No.
Yes. Though it won't be as hard as getting the armor in the first place.
You're still growing, but you won't reach that size.
I assume that dragons have biological immortality ala crocodiles?
Biologically immortal. Assuming a sustainable supply of food, no injuries, and no diseases, a crocodile can theoretically live forever, because they don't die of old age.
Yep. You're not unique in that aspect, though (some other creatures also don't die of old age).
Like crocodiles.
