this is worrisome

This is a non-animated picture.
They are used to relate to your pressure level. If you see them moving, then that means you have pressure.
The speed of the movement is the level of your pressure. The higher that moving speed, the higher pressure you have.
Most children and old men only see static pictures and not moving. If you see the pattern moving in a slow motion, that means you have a bit pressure at this moment.
Test yourself regularly with these pictures to know yourself better. Sometimes, it is good to have an appropriate pressure to push us to do better.
But too much pressure can push us to the end of the edge resulting in sickness.
Please calm yourself if you see those patterns moving fast.

*note: i see it moving. at a medium speed. now i`m worried. more so cause i don`t know why i would have pressure!
