Quick test to find out how old you really are!

Determining one’s age is not a straightforward business. Some people can be sprightly and energetic at 70, while others may look apathetic and permanently tired at 20. The age stated in one’s passport is not always reflective of someone’s actual age; a person’s internal biological clock can run at a pace different from that of his or her wristwatch!

Here’s a quick test you can do at home to work out a rough estimate of your true biological age.

Tests for figuring out your biological age:

  • 1. Heart

Check your pulse rate standing up. Do 20 sit-ups at a fairly fast pace. Check your pulse again. By how many beats has it increased?

— By up to 10 beats — your cardiovascular system is 20 years old.
— 10-20 beats — 30 years old.
— 20-30 beats — 40 years old.
— 30-40 beats — 50 years old.
— 40 or more beats — 60 years old.
— You didn’t manage to complete the sit-ups — 70 years old or older.

Excess weight can significantly affect test results.

  • 2. Nervous system

Your test partner should take a 50cm (20 in) long ruler, holding it with his or her thumb and index finger at the point, where 50 cm mark is located. The ruler should be in a vertical position. Place your hand approximately 10 cm (4 in) below the bottom end of the ruler. As your partner drops the ruler, try to catch it with your thumb and index finger as swiftly as possible. Note the mark at which you managed to grab the ruler.

— 20 cm (8 in) mark — your nervous system is 20 years old;
— 25 cm (10 in) mark — 30 years old;
— 35 cm (14 in) mark — 40 years old;
— 45 cm (18 in) mark — 60 years old;
— you failed to catch the ruler — 70 years old.

  • 3. Vestibular apparatus

Shut your eyes tightly (it’s important that you do so!) and stand on one leg, holding the other leg about 10 cm (4 in) off the floor. Remain in this position for as long as you can, with your test partner marking the time.

— If you manage to last for 30 seconds or more — your vestibular system is 20 years old;
— 20 seconds — 40 years old;
— 15 seconds — 50 years old;
— less than 10 seconds — 60 years old or older.

  • 4. Blood vessels

Using your thumb and index finger, pinch the skin on the back side of your hand and hold it for five seconds. A whitish spot will appear on the skin. Count the time it will take for the pale area to regain color.

— If it vanishes after 5 seconds — your blood vessels are 30 years old;
— 8 seconds — about 40 years old;
— 10 seconds — about 50 years old;
— 15 seconds — about 60 years old;
— more than 15 seconds — 70 years old.

  • 5. Joints

Clasp your hands behind your back and try to lock your fingers together at shoulder blades level.

— If this is an easy task — your joints are 20 years old.
— If your fingertips barely touch — 30 years old.
— If your hands fail to meet by a narrow margin — 40 years old.
— if you have difficulties bringing your hands together — 60 years old.
— if you’re unable to put your hands behind your back — more than 60 years old.

  • 6. Respiratory system

Light a candle. Now, let’s find out the maximum distance you can put it out from with one blow!

— 1 m (3 ft) — your lungs are 20 years old;
— 80–90 cm (31–35 in) — 30 years old;
— 70–80 cm (28–31 in) — 40 years old;
— 60–70 cm (24–28 in) — 50 years old;
— 50–60 cm (20–24 in) — 60 years old;
— Less than 50 cm (20 in) — 70 years old or older.

Summing it up:

Add up all the results and divide the total by the number of tests you’ve completed. The resulting value will represent your biological age.
