I have been working on it. Not necessarily the whole 'not dying' part but the part where our bodies self-regenerate, effectively making us ageless. We still have to eat, breathe, etc but biologically 'the parts won't wear out'. It is a work in progress, with myself as the guinea pig right now. Considering I am self-funded, it seems only fair. Until now, the only person I have told has been my wife, so feel privileged.
As a result, I have been thinking about what to do with my time in the event it works out. I have decided not to make a big deal out of it. I will continue to work as I am allowed, save up for 'retirement', and enjoy time with my children and grandchildren, and great-grandchildren, etc. I will spend what time remains in communities, like Asgardia, and enjoying my video games.
So, all in all, I don't think immortality would really change much for me. It would just remove the specter of death from my future, allowing me to make longer-term plans.
