So I have now finished, Philip K. Dick's "We can remember it for you wholesale" it is a great story. Do  find it. The shape of it is way above any of the movies. In fact the movies don't even fill in the missing parts of the original short story. The layering of a fantasy life and reality it just a joy to encounter. So to have saved the world by living is such a great idea. Wish more people did it. And, and  I didn't give the end away. I'm not that mean to ruin another man's story or life. Dyslexia rules. Have a great day.
