I think you know time goes faster the older you get. I'm sure you've heard it from others even if you don't think you have yet experienced it. So going after a few more years is like going after a few more cents in a world of dollars.
For all I know going after a million days may be the same but I'd like to find out.
Help me to find out, I don't think you can get it done without everyone involved and benefiting from it so we're all motivated.
I don't think you want to find out "the hard way" that a world effort is needed.
