list of things that matter:

Not that many things matter "in the big scheme of things" and, for your enjoyment/education, I will now type a list on digitalgoodness.info:

cleaning up the environment
global "government"
ending poverty
curing all disease
genomic medicine
space travel and exploration
measuring life in other areas of the universe

These things are 100% attainable. Strange.

oh, and figuring out the mystery that is time...
