The greater the visual impairment, the higher the melatonin level, the lower the estrogen levels and the lower the risk. Working night shifts or being exposed to low frequency electromagnetic radiation both suppress melatonin levels and unsurprisingly, increase breast cancer rates.
Roadmap to retirement: When your employer or plan changes. A private retirement plan can change its rules or terminate at any time. These changes can occur for a variety of reasons: during company mergers, to streamline plan administration, to improve plan features, or to reduce costs.
Full retirement age (also called normal retirement age) had been 65 for many years. However, beginning with people born in 1938 or later, that age gradually increases until it reaches 67 for people born after 1959.

The Congress cited improvements in the health of older people and increases in average life expectancy as primary reasons for increasing the normal retirement age.
