Age
Age is the length of time a person has lived, usually measured in years. Age affects many aspects of health, including metabolism, heart rate, and risk factors for certain diseases.
Real-Life Example
Consider a man who was born on March 15, 1993. Today's date is October 1, 2025.
- Age = 2025 − 1993 = 32 years
- Since March 15 has already passed this year, his exact age is 32 years and 6.5 months
Key Insight
Age is important because it influences metabolic rate, heart health, and recommended activity levels. For example, certain exercise intensity ranges and calorie needs are calculated based on age.
