British Medical Journal, 5 December 1998:1344 (news item): Do you get drunk at your holiday parties? Blame it on your mutant genes for neuropeptide Y. Mice bred to lack that enzyme became topers, while mice engineered to have it in excess wanted less alcohol, and went to sleep sooner. Might also work for dieters. Cheers, Joe -- J. R.
