    METs:
    A metabolic equivalent (MET) is a unit of measurement used to express the intensity of physical activity. One MET is defined as the energy expended while sitting at rest. This is equivalent to 3.5 milliliters of oxygen consumed per kilogram of body weight per minute (ml/kg/min).
    Activities with higher MET scores require more energy expenditure and are considered more vigorous. For example, walking at a leisurely pace has a MET score of 2, while running has a MET score of 10.
    The MET concept is used to classify exercise intensity into three levels:
    *Light-intensity activity:* 1.5 to 2.9 METs
    *Moderate-intensity activity:* 3.0 to 5.9 METs
    *Vigorous-intensity activity:* 6.0 METs or higher
    The Centers for Disease Control and Prevention (CDC) recommends that adults get at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity each week, plus two days of muscle-strengthening activities.
    Here are some examples of activities with different MET scores:
    MET scores can be used to estimate the number of calories burned during an activity. For example, a person who weighs 150 pounds and burns 5 METs for 30 minutes would burn about 180 calories.
    It is important to note that MET scores are just estimates, and the actual number of calories burned will vary depending on individual factors such as weight, body composition, and fitness level.
    Lee revised cardiac risk index:
    The Revised Cardiac Risk Index (RCRI), also known as Lee's score, is a tool used to assess the risk of cardiac complications in patients undergoing non-cardiac surgery. It was developed in 1999 by Dr. Thomas H. Lee and colleagues from the University of California, San Francisco. The RCRI is based on six risk factors:
    Each risk factor is assigned a point value, and the total score is used to stratify patients into risk categories.
    The RCRI is a simple and easy-to-use tool that has been shown to be effective in stratifying patients' risk of cardiac complications. It is widely used by surgeons and anesthesiologists to guide preoperative risk assessment and perioperative management.
    It is important to note that the RCRI is just one tool in the assessment of cardiac risk, and it should be used in conjunction with other clinical information, such as the patient's medical history and physical examination.
