That you can't understand why double and triple bonds are important for living things is beyond me. Strong bonds equals stable bonds. It's kind of a requirement for living things.
Why does it need to be particularly strong? Not all bonds in your body are double or triple. Most of them are single C-C and C-H bonds. If it were a matter of bond strength you'd get more mileage out of a Si-O bond. The enthalpy of that one is higher than C-C.
I will repeat again: most of the bonds in your body are SINGLE BONDS and...this is going to freak you out...your DNA makes EXTENSIVE USE OF hydrogen bonds! In fact it is kind of how DNA works. Hydrogen bonds are not the strongest bonds on the earth. In fact they are MANY TIMES SMALLER than even a C-C single bond.
So let's drop this cannard of "stable multiple bonds" as a definition of life. In fact it is arguable that most of life DOESN'T make use of those as much as they do the less strong bonds.
