Aging in waves: Key shifts at ages 44 and 60, shows study

Stanford researchers have discovered that aging occurs in distinct “waves” around ages 44 and 60. Their study, published in Nature Aging, found that biological changes intensified at these ages.

For example, people in their mid-40s experience shifts in how they metabolize alcohol and fats, which could lead to weight gain or increased sensitivity to alcohol.

By age 60, carbohydrate metabolism and immune function changes become more pronounced, potentially increasing illness risk.

The study suggests that building healthy habits earlier in life, like strength training and proper diet, might help manage these changes.
