DID Press: age 17 suggests that age 17 marks a critical turning point in human heart health.

Studies show that cardiovascular well-being begins forming in adolescence, with ages 18 to 25 being vital for developing lifelong healthy habits. However, fewer than one in four young people maintain a heart-healthy lifestyle during this period.
Habits such as proper nutrition, regular physical activity, and avoiding tobacco play a decisive role in preventing heart disease later in life. Yet statistics indicate that only 25 percent of youth sustain health-conscious behaviors as they transition into adulthood — while fast food consumption, physical inactivity, and use of tobacco and alcohol are on the rise.
Since 2010, heart disease rates among people under 40 have more than doubled. Experts warn that low awareness about risks like high cholesterol, obesity, and hypertension could expose the next generation to early heart disease.
