Dermatology Changes in the skin and subcutaneous tissues associated with growing older.  Ageing effects (e.g., patchy hyperpigmentation, fine wrinkles, telangiectasias) result from intrinsic and extrinsic processes and reflect the physicaleffects of the passage of time. Ageing skin is usually associated with a sagging face, in which deeper tissues (i.e., subjacent soft tissue) and structural landmarks lose their resiliency.
Geriatrics A multifaceted process in which bodily structures and functions undergo a negative deviation from the optimum. Ageing phenomena include decreases in memory, muscle strength, muscle mass, manual dexterity, cardiac output, and auditory and visual acuity, as well as loss or thinning of hair. Other ageing phenomena include increased body fat, and increased risk of cancer, diabetes, infections, osteoarthritis, and osteoporosis accompanied by a decrease in height due to decreased intervertebral space.

Intrinsic ageing The immutable effects of chronologic ageing, e.g., atrophy-attenuation of epidermis, retraction of rete pegs, decreased number of Langerhans’ cells and melanocytes, general decay of structural dermal and epidermal components
Extrinsic ageing Effects of external factors, e.g., sunlight, smoking, gravity and gravidity, keratinocytic dysplasia, solar elastosis, and possibly carcinogenesis; intrinsic & extrinsic ageing are intimately linked and thus not divided 
Ageing phenomena
Inevitable & immutable Cataracts, decreased skin elasticity, farsightedness, fibrous replacement of muscle, greying, poor recall, slowed intestinal transit, prostatic hypertrophy, wrinkling 
Inevitable but modifiable Baldness, cancer, reduced cardiac reserve, slow erection and ejaculation, decreased hearing, immunity, and vision, increased weight, liver spots (age spots), osteoporosis, decreased short-term memory, decreased stamina


The gradual accumulation of minor bodily injuries or degenerations often associated with a gradual decrease in functional capacity, that affects all human beings, to a greater or lesser degree, after middle age.

Patient discussion about ageing

Q. I would like to know the best age for pregnancy? Hi I am Deontae; I got married before 1 year. I and my wife planned to have a baby after 3 years. But now she is 25. I would like to know the best age for pregnancy? Which will help us to change our plan?

A. actually there is no best age for pregnancy (as far as i know), but some studies and research had shown that after 35 years old, a pregnancy is categorized as high risk, because there are some abnormalities and labor complication that are tend to happened (statistically) along with the increase of mother's age (such as: down syndrome, genetic disorder, post-partum bleeding, miscarriage, etc.)

so if your wife is now 25, i think you guys still have another 5-10 years to "accomplish" your family plan, hehehe...
Good luck, and stay healthy always..
