Can someone live forever

Answer 1

Good question, but unfortunately, it is impossible to live forever. Even with the healthiest lifestyle possible, metabolic rate starts to drop as we age. Combined with a gradually weakened immune system, we can't expect to live for eternity. The closest we can hope to achieve is to be cryogenically frozen once we die. This means freezing our bodies. Enzymes are destroyed by high temperatures, but aren't destroyed by freezing, so theoretically, we could still be brought back to life years later. However, research into this is still in its infancy.
