Doctor pointed to a simple way to identify the risk of early death in 30 seconds

Revolutionary 30-second chair test reveals risk of premature death, says renowned longevity expert Don Harper. In a conversation with HuffPost, the therapist shared a simple but effective self-diagnostic method available to everyone.

According to Harper, you can assess your body's biological age using an elementary exercise. You need to time 30 seconds and count how many times during this period you can stand up from a chair and sit back down. "The average 60-year-old man performs about 14 repetitions, and a woman of the same age - 12. If your result is significantly below normal, the risk of falls and premature death increases significantly," warns the specialist.

However, Harper notes encouraging news: the identified risk can be significantly minimized if you start systematic training with an emphasis on exercises that develop balance and endurance.

The expert also points to a natural decline in test performance with age. For people aged 65-69, 12 squats for men and 11 for women are considered normal. In the 80-84 age category, this indicator decreases to 10 for men and 9 for women. By the 90-year mark, men are able to perform seven squats on average, and women - four.
