Assume that you only have the resources and money that you’ve acquired up to this point in your life, and you still have to pay rent, bills etc. You are basically physically capable of everyday activities but extreme feats (eg running marathons, climbing everest) are not realistic.
I’d get started on all those “100 Things You Must ______ Before You Die” lists. I mean, I’d like to spend time with loved ones and prepare for the end, but they’re mandatory, apparently.
