A new study shows the number of people in the U.S. with Alzheimer's disease is expected to triple in the next 40 years.
The number of Alzheimer's cases is expected to rise so much because of the aging baby boomer population.
Experts say almost 14 million people in the U.S. could have Alzheimer's disease by the year 2050.
That's compared to fewer than five million in 2010.
Researchers say this increase will place a large burden on society in terms of the health care profession, and for caregivers at home.
A new study shows motorcyclists older than 60 are more three times more likely to be hospitalized from a crash than younger bikers.
The study authors don't know the exact reason, but they say reduced bone strength in older people may play a part.
They say it's also possible that since older people tend to have more disposable income, they're more likely to be able to buy a bigger, more powerful bike that could do more damage in a crash.
Researchers say older bikers have slower reaction times, worse balance, and vision problems that could make crashes more severe.
