Eternal LIfe

So I watched the Alias finale last night. Overall it was rather disappointing. The only thing I really liked about the show was the ending with Sydney and Vaughn on the beach. However, I thought it was interesting that one of the culmination of the of the major plot lines of the last 5 years was Sloane's (bad guy) quest for eternal life. He spent his whole life, millions of dollars, and countless lives solving a puzzle that in the end made him immortal. Unfortunately for him (good for the rest of the world) he got to spend eternity under a pile of concrete all alone. But it got me thinking, it's amazing what people will do, and have done in real history, in hopes of enternal life. And even more amazing to think that eternal life can be ours if we want it, we just have to accept the gift.
