Temperature rising, barometer falling, storm clouds moving in from the west. Watch out for melancholia, restlessness and nightmares"". This imaginary weather forecast opens this excellent examination into meteorobiology--the weather's effects on man, his health, humor, productivity, fertility, and crime-tendency. Weather is seen to affect us from time of conception and date of birth (brilliant babies being born as a rule in the early months of the year) to old age when the rapidly increasing oldsters of the nation would do well to retire southward where life is lived slowly and more peacefully. There are chapters that discuss weather and its effects on work; the dangers of too swift change from climate to climate (via airtravel); the benefits of January vacations in the south; and, finally, a plug for birth control that would ensure birth at the most auspicious time of the year. Interesting and fully substantiated by clinical and laboratory findings, this should prove provocative.
