***These are all false.***
 Menopause- the time of natural cessation of
menstruation; also refers to the biological
changes a woman experiences as her ability to
reproduce declines.
 Life Expectancy has increased
Life Expectancy
from 49 years in the midtwentieth century to 67 in the
early twenty-first century, and in
some developed countries it
exceeds 80.
 These increased life expectancy
can be due to healthier, wealthier
environment.
 Life expectancy differs for males
and females
 Males more prone to death, at

There has been many speculation
of why people age so quickly,
one theory states that we pass
on our genes most successfully
when we raise our young and
stop consuming resources.
Sensory Abilities
 Many of our sensory abilities decline as we age.
 Visual sharpness, adaptation to light changes, muscle strength,
reaction time, stamina, sense of smell, hearing, and distance
perception all diminishes as we get older.
 The decline in sight is due to the fact that with age, the eye’s pupil
shrinks and its lens become less transparent, so as a result it reduces
the amount of light that reaches the retina.

For example, a 65 year old person’s retina only receives about one third as much
light as a 20 year old person's retina.
