Health
Young/prime adulthood can be considered the healthiest time of life and young adults are generally in good health, subject neither to disease nor the problems of senescence. Biological function and physical performance reach their peak from 20–35 years of age, waning after 35. Strength peaks around 25 years of age, plateaus through 35 - 40 years of age, and then declines. Flexibility also decreases with age throughout adulthood. However, there are large individual differences and a fit 40-year-old may out-compete a sedentary 20-year-old.
Women reach their peak fertility in their early 20's. Assuming unprotected intercourse with a man of the same age, women aged 19–26 have about a 50% chance of becoming pregnant during a given menstrual cycle, compared with 40% in the 27-34 age group and below 30% for women 35-39.
In developed countries, mortality rates for the 18-40 age group are typically very low. Men are more likely to die at this age than women, particularly in the 18-25 group: reasons include car accidents, and suicide. Mortality statistics among men and women level off during the late twenties and thirties, due in part to good health and less risk-taking behavior.
Regarding disease, cancer is much less common in young than in older adults. Exceptions are testicular cancer, cervical cancer, and Hodgkin's lymphoma. In sub-Saharan Africa, HIV/AIDS has hit the early adult population particularly hard. According to a United Nations report, AIDS has significantly increased mortality of between ages 20 to 55 for African males and 20 to 45 for African females, reducing the life expectancy in South Africa by 18 years and in Botswana by 34 years.

Famous quotes containing the word health:
“Men’s hearts are cold. They are indifferent. Not all the coal that is dug warms the world. It remains indifferent to the lives of those who risk their life and health down in the blackness of the earth; who crawl through dark, choking crevices with only a bit of lamp on their caps to light their silent way; whose backs are bent with toil, whose very bones ache, whose happiness is sleep, and whose peace is death.”
—Mother Jones (1830–1930)
“Nothing in Nature’s sober found,
But an eternal health goes round.
Fill up the bowl, then, fill it high,
Fill all the glasses there—for why
Should every creature drink but I?
Why, man of morals, tell me why?”
—Abraham Cowley (1618–1667)
“Medication alone is not to be relied on. In one half the cases medicine is not needed, or is worse than useless. Obedience to spiritual and physical laws—hygeine [sic] of the body, and hygeine of the spirit—is the surest warrant for health and happiness.”
—Harriot K. Hunt (1805–1875)
