Early: Aged around 20 to 30 Middle: Aged around 30 to 65 Late: Any age after 65*
Physical decline increases as age increases. Those who exercised constantly when younger will have better athletic prowess (exceptional skill and ability) than those who barely exercised.
Aging lessens sexual desire as well as fertility in women, explaining why it is harder to get pregnant when older. In addition, women also go through menopause (the lessening of getting periods and lower pregnancy rate).
Sensory abilities differ vastly between the different stages of adulthood, including sight, smell, and hearing. Neural processing also slows over time and when combined with lowered sensory abilities, higher accident rates tend to occur.
Immunity and antibodies in the blood weaken over time. Older people are more prone to illness because of this.* Frontal lobe atrophy causes a gradual declination of memory and inhibition.*
Through the use of an exercise regimen, older adults can reduce the risk of dementia since exercise boosts the development of neural connections and the birth of nerve cells. As a result, memory is enhanced and so is judgement.
