Modern technology has also revolutionized many other basic needs of social life. The constant fears of pollution from radiation and the uses to which nuclear power may be put diminish the pleasure and relaxation man derives from nature, and also breed dismay for the welfare of future generations. Eating customs and dietary habits are influenced by the availability of pre-prepared foods, often hurriedly taken while standing at a 'bar'; leisure and recreation are dominated by television and other spectator pursuits; the pattern of working life is dictated by the pace, monotony, and programme of automated machinery; and accelerated transportation not only brings infectious diseases to previously uncontaminated districts, but also increases motor accident rates and separates home and workplace, thus adding the additional stress of commuting.
