In a study of more than 500 people, experts found that 15-year-olds with high cholesterol levels can normalize those levels by their mid-30s, emphasizing the importance of targeting teens with health campaigns, the BBC reports.

But those who upped their body weight or started smoking were more likely to maintain risk levels.
