Surprisingly, though, an AARP-sponsored poll suggests people are starting to settle on a number to define old.. In 1974, nearly half of those polled said that age depends on a person's health or some other factor. By 2004, only 5 percent said that.

Hearing a heartbeat in your ears can indicate a hardening of the blood vessels in the neck. In this video, Dave Salley, MD, an ear, nose and throat specialist at Chippenham & Johnston-Willis Hospitals, discusses what other noises you might hear, and what they mean.
What's a normal heartbeat? Your heart is made up of four chambers â two upper chambers (atria) and two lower chambers (ventricles). The rhythm of your heart is normally controlled by a natural pacemaker (the sinus node) located in the right atrium. The sinus node produces electrical impulses that normally start each heartbeat.
