I am going to assume that money is probably the most important thing to enable me longevity. So, anything I do must correlate with wealth, but I also want to be in a good position for the future as well. Computers will eventually replace humans in all industries, except things that are creative like art/writing/music or highly technical. But even the medical field is being outsourced, every field is being outsource.
If I live forever, then I could always return to college down the road as well... so I could take a 5 year risk right now quite easily. I do not have plans on having children either.
1. Education/college/improving the mind - no wealth today, but possible good money down the road, but then... computers will replace my education/knowledge, and it will make it all worthless by time 2040 rolls around. Therefore money is all that matters when the time comes.
2. Work hard today for money doing whatever possible to get this wealth, and if I choose this route I can predictably see 50k a year for a while, but it's not going to be pretty..... I would try to make myself as rich as possible in the next 10 years, and then try to create passive avenues for wealth.
