My mind is quite made up (as in decided, not fictional).
I know I will not be coming back, but back to what do I have to come? I have no earthly attachments. In the last 10 years I have seen my friends once and my family twice. If I am going to be alone, I may as well be alone on the journey of a lifetime.
They have Internet and I will still be able to stay in touch and even post here.
I have moved around the world several times to keep up the change in pace. Moving to Mars would be a final change in pace but it would be so major I wouldn’t need any more changes. Different sky, different moons, different gravity, a life of exploration and discovery, and being part of a major milestone for humankind.
I’m alone no matter what. May as well do all that.
