Senior Health Why are 95% of people who live to 110 women? ♦ :Light-intensity exercise could prove beneficial to older adults, ♦ Partial sleep deprivation linked to biological aging in older adults

Why are 95% of people who live to 110 women? You're as old as your stem cells Human super centenarians share at least one thing in common--over 95 percent are women. Scientists have long observed differences between the sexes when it comes to aging, but there is no clear explanation for why females live longer. In a discussion of what we know about stem cell behavior and sex, researchers argue that it's time to look at differences in regenerative decline between men and women..
As baby boomers age, do their decisions get better or worse? As an economic and political force, researchers say that older adults hold a tremendous amount of social power in the United States. A new study is examining what factors contribute to older adults’ decisions.
Light-intensity exercise could prove beneficial to older adults, An easy walk, slow dancing, leisurely sports such as table tennis, household chores and other light-intensity exercise may be nearly as effective as moderate or vigorous exercise for older adults -- if they get enough of that type of activity.
Partial sleep deprivation linked to biological aging in older adults One night of partial sleep deprivation promotes biological aging in older adults, a new study suggests. One night of partial sleep deprivation activates gene expression patterns in peripheral blood mononuclear cells (PBMCs) consistent with increasing accumulation of damage that initiates cell cycle arrest.
