Introduction to Aging (HTML Version)
Is Aging Irreversible?

Is Aging Irreversible?
Our current understanding is that the changes of aging cannot be prevented or reversed.

Is Aging Preventable?

Is Aging Preventable?
Changes of aging cannot be prevented or reversed, but many may be minimized or delayed by a healthy lifestyle.


Is Aging Gradual?

Is Aging Gradual?
Humans age gradually over an entire lifetime of small changes in our bodies' molecules, cells, tissues, organs and systems. Some species, like the giant tortoise, age so slowly, they barely appear to age at all!

Is Aging Sudden?

Is Aging Sudden?
A few species, like Pacific salmon, experience aging as a sudden and dramatic change. After their first and only migration to spawn, these fish rapidly age and die.

Is Aging Universal?
Similar molecular and cellular changes of aging are found throughout the animal kingdom, including animals as tiny and simple as this roundworm.

Is Aging Individual?

Is Aging Individual?
All individuals in a species experience the same basic changes of aging, but each individual's experience is unique. Each body has its own timetable for aging.

Is Aging Disease?
Aging is not a disease, but the risk of disease increases with age.

Is Aging Health?

Is Aging Health?
Health persists during normal aging. Healthy aging is a gradual process of slowing down while essential functions remain intact.


Is Aging Loss?

Is Aging a Loss?
Aging is a gradual decline in our bodies' physical functions. For example, as elephants grow old their teeth wear out, and their movements slow down.

Is Aging Gain?

Is Aging a Gain?
Although aging is defined as physical decline, it contains the opportunity for gain in knowledge, wisdom, well being, creativity, relationships, and experience. Mature elephants are more successful herd leaders because of their long experience.


Is Aging Genetic?

Is Aging Genetic?
Many changes of aging may be influenced by our genes. For example, the life spans of laboratory animals have been extended by altering their genes.

Is Aging Environmental?

Is Aging Environmental?
Studies of identical twins who have the same genes indicate that environment determines nearly 75% of our health and longevity.
