Because the chemicals in them would damage your skin because of the structure of your skin cells.
To men, there are acne and breast development, to others it could be life-threatening, like liver cancer or heart attacks.
Answer:
Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates. The creatinine clearance decreases with age although the serum creatinine level remains relatively constant due to a proportionate age-related decrease in creatinine production. Functional changes, largely related to altered motility patterns, occur in the gastrointestinal system with senescence, and atrophic gastritis and altered hepatic drug metabolism are common in the elderly. Progressive elevation of blood glucose occurs with age on a multifactorial basis and osteoporosis is frequently seen due to a linear decline in bone mass after the fourth decade. The epidermis of the skin atrophies with age and due to changes in collagen and elastin the skin loses its tone and elasticity. Lean body mass declines with age and this is primarily due to loss and atrophy of muscle cells. Degenerative changes occur in many joints and this, combined with the loss of muscle mass, inhibits elderly patients' locomotion. These changes with age have important practical implications for the clinical management of elderly patients: metabolism is altered, changes in response to commonly used drugs make different drug dosages necessary and there is need for rational preventive programs of diet and exercise in an effort to delay or reverse some of these changes.
Answer:
The answer is: hidden testes
Explanation:
Testes - this is also known as <em>"testicles."</em> T<u>his refers to the oval-sized organs of the male reproductive system that is responsible for producing sperm.</u>
Hidden testes is also known as <em>"undescended testes." </em>Medically speaking, this is called<u> "Cryptorchidism." </u>This commonly affects <em>very young boys, especially those who were born prematurely</em>. This means that the testes couldn't fully descend on the 7th month of gestation (when it is supposed to).
Most of the time, only one testes cannot descend, but in some cases, both testes cannot descend, although it only accounts 10% of those with this disorder. Having undescended testes means that the male's sperm production is disrupted. <u>The production of sperm requires a certain temperature that is lower than that of the body temperature.</u> It's location should be outside and not inside.
