Do You Think It's a Good Idea to Live Longer?

I'm not so much about which ethical part do you think we should talk about? The ethics that I haven't got clear in my head yet to where I stand one way or the other is this whole idea of editing genes. So looking at the sort of the mechanics of how every life works, because the chemical processes that make humans work are the same systems in dogs and cats and tortoises and whales. But they're different combinations of them and they've evolved to do different things. If we now start engineering that and turning things off or turning things on adding things that haven't come there through natural evolution, where does that kind of end up?
