SPECIAL RELATIVITY OF TOURISM
Time travel is the best kind. You don’t have to move a muscle or start an engine. You just flip the pages of memory and sit back and enjoy as images pass by on the projection screen of your mind’s eye. There’s only one drawback; it involves getting old. So, as with most of life itself, it all works out in the long run; the less you’re able to travel in space, the more you’re able to travel in time. Don’t laugh at that old guy with spit dribbling down his chin; he’s trucking in his mind.
