This is a health test in which the tester provides some data about their physical condition, submits it to a machine for a comprehensive evaluation, and ultimately calculates your life expectancy. Friends who are interested can take the test. The entire test takes about 5 minutes and mainly requires users to provide information such as height, weight, age, work intensity, blood pressure, blood sugar, blood lipids, exercise conditions, etc. At the end of the test, your "time of death" and life expectancy "countdown" will be displayed to remind you to pay more attention to your physical health. The webmaster recommends that friends who are overly worried about their own health or have an excessive fear of death should not take the test.
