Why do larger animals have longer lifespans?

Question

Small animals like hamsters only live 2-3 years (as pets) while animals like crocodiles live on average for 30 to 40 years. Is it because their bodies age or get weaker slower because they have a larger surface area or something?

Thanks for answering
