Old people over 60 are not suitable for practicing handstand. With the increase of age, the elasticity of blood vessels will gradually weaken. This is a natural law, and it has nothing to do with them not practicing when they were young. The only question is how quickly they weaken. When they stand upside down, their head blood pressure will be much higher than normal, and it will suddenly rise when they enter the upside down state, which will easily lead to the rupture of blood vessels in the head and the serious consequences of cerebral hemorrhage.
