I suspect that people who like to say that they would like to live "forever" or think that they would be interested "endlessly" in new things have not really thought through what infinity means. You might want to check Grahams number. And then spend a while thinking that even that number is not even a microscopic fraction of infinity.
And if you still think you want to live forever. How on earth are you going to use your puny 100 billion neurons to experience, store and decide the order of experiencing and studying the endless Graham numbers of curiosities without at some point getting into a loop after you have had your brain in every single possible state? And when your brain has been in every possible state for say a billion times, you think it is not going to get boring?
