Coffee drinking may help thinking skills as women age

According to a study published in the journal Neurology, active coffee drinkers over the age of 65 (who drank at least three cups of coffee a day) had demonstrably less decrease in memory functioning than women who drank only a single cup.

The study surveyed 7,000 women over a period of four years. Surprisingly, the effects of the caffeine increased as the women aged, with 30% less likely to suffer memory decline at 65, rising to 70% at age 80.

The study only looked at memory functioning, not at dementia, with the rates of dementia (Alzheimer’s) constant and unaffected by caffeine intake in the study.

Mice Use Less Sunscreen – Substitute Coffee and Exercise Instead

Who would have guessed that coffee and exercise induce the formation of cells that block sunrays? But they do–at least in mice.

As reported in the Proceedings of the National Academy of Science, hairless mice who were fed high doses of caffeine, and exercised on their running wheels, showed an increase in the cells which protect against sunburn.

There have been no human studies to date, so you may wish to continue your sunscreen, hats and shirts before switching to double espressos on the beach.
