• States with vision testing of elderly drivers have a lower rate of fatal automobile crashes involving the elderly than do other states. [102]
• In California, physicians are required to report patients with dementia to the state driving board. [116]
• No specific references here yet, but remember, ???? parkinsonian patients can move normally when there is a sudden emergency. [117]
• By coincidence, 22 patients with stable cardiac disease drove into a radar trap while wearing a Holter monitor. All reported some cardiac symptoms, such as tachycardia. In the group as a whole, an increase in ventricular ectopy was seen. Two patients had runs of ventricular tachycardia (18 and 25 beats, respectively) and 4 had myocardial ischemia. The authors acknowledge that the risk of dying in an autmobile mishap is probably higher than the cardiac risk imposed by speed traps. [119]
• For other spy signs, see card TH-006. [121]
• We have seen that physicians, spies, and journalists observe humans closely. Cervantes would have us add another category: nervous lovers. Don Quixote's flowery speech is too long to type, but it ends with:

  For you must know, Sancho... that between lovers the outward actions and movements they reveal when their loves are under discussion are more certain messengers, bearing news of what is going on in their innermost souls.
