I ordered one about a week ago. It arrived in the mail today with a short note of instruction:
Congratulations on purchasing the Syndaver(TM) deluxe "simulated" cadaver! We think you'll find it so close to real you'll think it IS real. We assure you, it's not. However, because we've simulated the human cadaver so accurately, we'd like you know that it will begin to rot and decay, and, quite frankly, stink up the place. So please conduct your experiments and practices within 48-64 hours of receipt under normal conditions of temperature and humidity. You can prolong the use of your Syndaver(TM) by as much as two weeks if you store it in a very cool and dry environment.
