If the TARDIS travels through time, and the Doctor can travel to anywhere at any time, then why is the Doctor always running and in a hurry.
And in Star Trek, every time someone is transported, you actually see them die, only to be cloned and reformed at the other end of the transport. By transporting someone you can remove any foreign bacteria and viruses from the transport. A Memory pattern of the person is kept in storage when the person is transported. So if you had someone die (say, spock) whether from injury, disease or whatever, you should theoretically be able to put the body in the transport, overwrite the information with a pattern from memory and you would remove any disease, injury or whatever killed them, only to reform them in their prior state, perfectly fine.
No one should be able to die in Star Trek, ever. With all the technobabble that goes on, this is a very logical function of the parameters set onto transporters.
