Newton's first law of motion. Body in motion remains in motion
So cant get stuck if i never sit down, keep on moving. Start in the morning and drop dead in the evening, never sit down too long in the meanwhile.
Though yeah probably not that helpful in getting into motion again once stuck. Body in rest remains at rest
Warning: not the healthiest approach

Though i do understand you, had the same issue when growing up, eventually went on to become kinda debilitating as i couldn't speak to her at all. Though there is some fault on her as well as she was kinda explosive and unpredictable. Never spoke to her about it, didn't have the balls/guts.
