When does old age start


Ageing is inevitable,we know,but the latest theory suggests that different parts of our body actually age at different times,most bodily functions peak shortly by 30 and then begin a gradual but continuous decline.
Muscle(begin at ageing 30)
The amount of muscle tissue and strength tend to decrease with ageing called sarcopenia loss of muscle mas begin around 30 and continues through tout life.It causes the metabolic rate to slow down,resulting in reduced calorie burning and increased body fat levels,regular exercise can significantly delay that.
Brain(begins ageing at 30)
the brain shrinks in size,and neurons in certain areas are lost or become faulty,blood flow to the brain decrease,most people notice subtle changes in their connective abilities.They take longer to think throe a problem on make a calculation .
eyes(begin the age 30)
The pupil reacts more slowly to changes in light.The eyes produce less fluid making them feel dry.
Ears(being ta age 40)
changes in hearing prob lay due to as much to noise exposure has to aging.hearing high pitch to sound ,such as women and children talk becomes more difficult has one grows older.
