### failure | loss:

Bone loss
* Most bone loss is influenced by hormonal deficiencies.
* Some bone loss is normal as people age
  - normal part of aging
* accelerates with advancing age.
* affects both cortical and trabecular bone.
* associated with smoking increases the risk of hip fractures.
* begins earlier in women than in men and speeds up after menopause.
* can also limit the amount and direction of tooth movement that is advisable
  - develop due to a decrease in estrogen levels, increasing the risk for osteoporosis
  - occur all through the body or in one specific area
  - take place without any symptoms until a fracture occurs
* frequent complication after liver transplantation.
* increases dramatically during the middle years and especially for women
  - rapidly after menopause and can contribute to osteoporosis
  - the most during the menopause years
* is associated with both periodontal disease and osteoporosis.
* is caused by consuming too much animal protein, which leaches calcium from the body
  - the decrease in estrogen which occurs with menopause
  - common as people age
  - due to the acid nature of meats, eggs, poultry, cheee
  - evident in a large number of individuals that drink heavily
  - greater in women
* is greatest during the first five years of menopause
  - in women following the menopause
  - within the first few years after menopause
  - inevitable and a normal part of aging
  - most dramatic during the first two or three years after menopause
  - normal with aging, but it accelerates dramatically without estrogens
* is one of the consequences of extraction
  - major physiological 'show stoppers' in sending humans to Mars
  - reversible when glucocorticoid treatment is withdrawn
  - usually a painless process until a fracture occurs
* leading cause of fracture, especially in women.
* leads to a weakened skeleton incapable of supporting normal daily activities
  - numerous problems aesthetically and functionally
* occurs as a result of an imbalance between osteoblasts and osteoclasts
  - most rapidly in the first five years of menopause
* occurs when estrogen levels are decreased
  - the action of osteoclasts exceeds that of osteoblasts
  - with age in all individuals
* occurs without signs and symptoms
* problem for astronauts as well.
* serious problem for many older people, especially women.
* starts as soon as six months from loss of menstruation
  - to occur in most women from the mid thirties
  - within six months to two years of the loss of menses and it's irreversible
* tends to be greatest in skeletal sites with the highest concentration of trabecular bone
  - increase with increased glucocorticoid doses and prolonged use
* very common problem for women with anorexia nervosa.

Crop loss
* are due primarily to larvae feeding and premature fruit drop.
* can be significant in years with rainy springs.
* is correlated with dry mass of mallow rather than the number of plants.

Epilation
* is loss
  - the process of removing unwanted hairs
* works by causing a small scar around the treated hair.

* is the real indicator for a true measure of weight loss.
* requires a long-term commitment to eating right and leading a healthy, active lifestyle.

Capital loss
* are deductible from capital gains and, to a limited extent, other income.
* is financial loss.

Fluid loss
* can cause numerous problems in the body
  - occur from common conditions such as diarrhea or vomiting
* causes blood flow to decrease in the vital organs, resulting in a form of shock.

Forest loss
* Is job loss.
* predict bird extinctions in eastern North America.

Friction loss
* develops much more slowly than the change in water velocity.
* is caused by what in pipe.
* occur as water flows through fire sprinkler piping.
