1. Much research is being conducted on repairing faulty sensory organs through devices such as personal guidance systems and eyeglasses, among others. Do you think that researchers should attempt to improve normal sensory capabilities beyond their "natural" range?
2. Suppose that a new "miracle pill" will allow a person to function with only one hour of sleep per night. However, because a night's sleep is so short, a person who takes the pill will never dream again. Knowing what you do about the functions of sleep and dreaming, what would be some of the advantages and drawbacks of such a pill from a personal standpoint? Would you take such a pill?
