<span>Using performance-enhancing drugs has various long-term
effects that includes worsening acne, impotence, balding, stunt growth in
adolescents, increased risk of blood clot and more serious effects such as
heart and liver damage. When the liver
is impaired, it can result to swelling of legs, arm and abdomen, worst case is
jaundice. Meanwhile, damage heart will lead to increase risks of high blood
pressure, heart attack and stroke.</span>
I think this is multiple choice, and if it is, your answer is Don't do it yourself
Answer: 2.0 years
Explanation:
NOTE:
17% of the U.S. population lives in rural areas, while 83% in urban areas.
During the past 40 years, there is a consistent overall increase in U.S. life expectancy from 70.8 years in 1970 to 78.7 years in 2010. However, a decade ago, a study reveals the rural-urban gap widening from 0.4 years in 1969 through 1971 to 2.0 years in 2005 through 2009.
Study showed that 70% of the overall rural-urban gap in life expectancy and 54% of the life expectancy gap between the urban rich and rural poor in 2005 to 2009 are caused by accidents, cardiovascular disease, COPD and lung cancer.
A combination of factors likely accounts for this disparity. Compared to urban areas, rural areas have higher rates of both smoking and lung cancer, plus obesity, yet reduced access to health care services. Also, rural dwellers have a very low median family income, higher poverty rate and very few have college degrees.

Local anesthetics inhibit nerve conduction in a reversible manner without altering the nerve. The inhibition appears rapidly and for a longer or shorter duration depending on the products and the concentrations used. The extent of the territory rendered insensitive to pain depends on the modes of administration of the local anesthetic, either at the level of the nerve endings, or at the level of a nervous trunk, for example.
They act at the level of the neuronal membrane by interfering with the process of excitation and conduction. The anesthetic crosses the axon membrane, rich in lipids, in the form of base before taking up a cationic form on the internal face of the neuron where the pH is more acidic.
At this level, there is a blockage of nerve conduction by decreasing the membrane permeability to sodium ions that occurs during the depolarization phase. As the progression of the anesthetic action along the nerve increases, the threshold of excitability increases and the conduction time increases. This is completely blocked from a certain concentration of local anesthetic.
The nerve fibers are unequally sensitive to the action of local anesthetics: they disappear in order: the painful, thermal, tactile sensations.
