I used to think, when I was a child, that it was an awful thing to have to go on breathing and breathing, all my life until I was dead, all those thousands of years. And then I used to think that now I was conscious of breathing it would be like everything else where I did it without thinking for a while and then became aware of it, and it would be awkward and difficult to do it as well consciously, and then by the time I had thought that I used to realize that while I was thinking it I had been breathing.
