One new study found that baby boomers (ages 49 to 67 in 2013) are living longer than people roughly 20 years older, but are not healthier.1 While they are less likely to smoke, have emphysema, or a heart attack, they are more likely to be obese, have diabetes, or high blood pressure than the previous generation at similar ages.
Today, the oldest Boomers are approaching their â60s, and once again, America is preparing for a paradigm shift. The most commonly accepted definition of the Baby Boomer Generation is that it comprises people born between 1946 and 1964. 1946 marked the start of the increase of births in America, and the numbers, while peaking in 1957, remained steady until they finally began to drop in 1965.
