Collagen
The body produce a substance called melanin which makes your skin and hair darker. As your body ages, the amount of melanin in the hair decreases and the hair gets lighter.
When energy balance in the body is positive body mass decreases
Yes, the flexibility of the body is closely related to its degree of elasticity. Elasticity refers to the ability of muscles, tendons, and ligaments to stretch and return to their original shape, which contributes to overall flexibility. Greater elasticity allows for a wider range of motion in joints and muscles, enhancing flexibility and reducing the risk of injury during movement. Therefore, improved elasticity can lead to increased flexibility in the body.
The body starts to shiver, and your hairs raise to try and keep the heat in, causing the effect known as 'goosebumps.' Very slowly the body's temperature decreases from the normal 36 C - 37 C.
Body water percentage generally decreases with age. Infants have a higher percentage of body water, around 75-78%, which declines to about 50-60% in older adults. This decrease is due to factors such as changes in body composition, including increased fat and decreased muscle mass, as well as hormonal changes. Therefore, rather than increasing, body water typically decreases as a person ages.

It is normal to have minimal bruising during menstruation. Decreased estrogen levels during menstruation cause a loss of the blood vessel's elasticity in the body. This can cause small leaks that can turn into small bruises. Anything more serious or that last past the cycle should be looked at by a doctor.
When the artery walls lose their elasticity, this is called arteriosclerosis. When this happens, the body has a tougher time circulating blood.
After exercise, the body's need for oxygen and energy decreases, causing the heart rate to slow down. This is because the muscles no longer require as much blood flow and the body is no longer under stress.
