What is the point of adult relationships when you can die at any time

You could get into an accident. You could get a cold and it could turn out to be a deadly cold. So what's the point of forming relationships? What's the point of making friends? What's the point of having sex? What's the point of making a family? It's all going to die anyway. What's the point of trying to make the best of life? What's the point of trying to be a happier person? You're gonna die and nobody even cares. You're nothing. We're all nothing. Our lives mean nothing.
