There are plenty of people who wish of having immortality on this Earth, but that to me a painful curse. Sure, you get to have the benefit of doing what you want, however you want, but before you go out wishing for the ability of eternal life, think about what will happen. What happens when you run out of things to do? Everything is finite. Do the people around you become immortal as well? If not, then everyone you have and ever will know, will eventually pass away without you.
