I question has been really naggin at me for quite awhile.

Just how strong and durable are Ranma and Ryouga?
In some fanfics, they can be killed by cars, trucks, and bullets.
However given the description of their stamina and strength in the manga and
anime, they should be able to withstand such attacks or at least dodge them.

Can anyone actually prove them Ranma or Ryouga can be killed by a car hitting
them or by getting shot?
