Healthy Lifestyle – Aging Causes and Process for Body Parts

Most of our all body parts ages at different times.

(1) Liver :-

It starts aging at 70 years age.

This is the only organ in the body which seems to defy the aging process.

(2) Kidneys :-

It starts aging at 50 years age.

With kidneys, the number of filtering units (nephrons) that remove waste from the bloodstream starts to reduce in middle age.

(3) Prostate :-

It starts aging at 50 years age.

The prostate often becomes enlarged with age, leading to problems such as increased need to urinate.This is known as benign prostatic hyperplasia and affects half of men over 50, but rarely those under 40.

(4) Bones :-

It starts aging at 35 years age.

'Throughout our life, old bone is broken down by cells called osteoclasts and replaced by bone-building cells called osteoblasts - a process called bone turnover’. Children's bone growth is rapid - the skeleton takes just two years to renew Itself completely. In adults, this can take ten years.Until our mid-20s, bone density is still increasing. But at 35 bone loss begins as part of the natural ageing process.

(5) Teeth :-

It starts aging at 40 years age.

As we age, we produce less saliva, which washes away bacteria, so teeth and gums are more vulnerable to decay. Receding gums - when tissue is lost from gums around the teeth - is common in adults over 40.

(6) Muscles :-

It starts aging at 30 years age.

Muscle is constantly being built up and broken down,a process which is well balanced in young adults.However,by the time we are 30,breakdown is greater than build up.One adults reach 40,they start to lose between 0.5 and 2 percent of their muscle each year.Regular exercise can help to prevent this.

(7) Hearing :-

It starts aging at 50 years age.

More than half of people over 60 lose hearing because of their age.

(8) Skin :-

It starts aging at 20 years age.

The skin starts to age naturally in your mid-20s.

(9) Taste and Smell :-

It starts aging at 60 years age.

We start out in life with about 10,000 taste buds scattered on the tongue.This number can halve later in life. After we turn 60, taste and smell gradually decline, partly as a result of the normal aging process.
