...idea of implanting brain stem cells, while not as dramatic as swapping whole brains, also raises intriguing philosophical questions. "Sometimes at seminars when I talk about my work," says Snyder, "somebody will ask me whether the introduction of these stem cells will alter memory." Do the newly generated cells distort or erase old memories? Or will the transplanted stem cells bring with them memories of their upbringing in a Petri dish...
...this is meta-neuroscience," says Snyder, laughing. "But I tend to think that the cells will take their cue from the host that houses them" rather than remembering their past lives like so many cellular Shirley MacLaines.

We can do it by moving down the food chain: eating foods that use less water and land, and that pollute far less, than cows and pigs do. In the long run, we can lose our memory of eating animals, and we will discover the intrinsic satisfactions...
