One test, you know your age now! Super accurate!

Read one side:

[1] First, pick a number (0-7) to indicate the number of times you want to walk out every week.

[2] Multiply this number by 2

[3] Then add 5

[4] multiply by 50

[5] If your birthday has passed this year, add 1757 to the expected number. If not, add 1756.

[6] In the last step, use this number to subtract the year you were born.

[7] Now you have a three-digit number.

[8] the first digit is the number you selected at the beginning (that is, the number of times you want to go out every week)

The next two digits are your age. It's time to go to the top!
