Imagine you could have any automobile of your choice. It would be your only auto and would have to last you for an entire lifetime. If it wore out, it could not be replaced. Once gone, you would be reduced to other methods of getting around, or borrowing rides from other people. One car and only one for your whole life.
Would you take care of your car, or would you abuse it?
Would you change the oil regularly, keep it clean, park it in a garage?
Of course you would take the best care you possibly could of your vehicle. No going out to the drag races on Friday night. Only premium fuel for your motor. Tune-ups, antifreeze, lubrications, maintenance — always you would choose nothing but the best for your automobile.
Would you let your auto sit idly for a year? Never.
Would you push it to the limits to find out how fast it could go, or what the roughest terrain is that it could possibly handle? Absolutely not.
If you were given only one car for a lifetime of use, it is clear that you would never abuse it; you would always take the best care of it you possibly could. You would provide all the necessary maintenance and care your car needed and deserved. Right?
What if you had only one body?
