Women, Retirement Planning, And Life Expectancy

Women, more than men, say they expect to live past the age of 90. In fact, nearly twice the number of women said they expected to live a long life compared to men in a recent retirement survey. But despite having expectations of living longer, many women haven’t planned adequately for the financial requirements associated with increased longevity. For example, more than half of surveyed women said they respond to financial emergencies by dealing with them when they occur rather than planning for possible scenarios. But though women participants said they didn’t plan in advance, more than 70 percent admitted to being very or somewhat concerned about providing for their long-term care needs. The study highlights the need for women to be properly prepared for their financial needs in retirement. More here.

Men, Women, And The Effects Of Alzheimer’s Disease

New research from the University of Hertfordshire found that women with Alzheimer’s disease tend to deteriorate faster than men with the disease. The paper, published in the Journal of Clinical and Experimental Neuropsychology, discovered men consistently scored higher on a series of cognitive tests and outperformed women in verbal and visuospatial tasks. Keith Laws, professor of psychology, said Alzheimer’s specifically disadvantages women, unlike with normal aging where women tend to decline more slowly than men. Alzheimer’s disease, according to current estimates, affects 30 million people worldwide with 4.6 million new cases every year. Women are more prone to the disease than men, though the reason behind the gender-based differences in decline are unknown. More here.

Genes Answer Question Of Why Women Outlive Men

Research from the Monash School of Biological Sciences and Lancaster University found that genetic variations in mitochondria may explain why women outlive men by an average of five to six years. Mitochondria exist in almost all animals and help to convert food into energy. But the study found numerous mutations to mitochondrial DNA that affected the speed at which males aged and how long they lived but had no similar effect on women. The researchers said that the difference could be explained by the way genes are passed from parents to their children. Researcher Dr. Damian Dowling said children only receive mitochondrial genes from their mothers, which means any mutation that only harms males will go unnoticed due to evolutionary quality control or natural selection.
