Knots have the element of surprise. Massage clients are often very perturbed that they have a knot, and then the inevitable question…why is that knot there?
That said these older knots seem to be more than simply forgotten dysfunctional areas of muscle. Something has happened along with the formation of the knot to make it last. Perhaps, if knots form like memories, they become more robust when a person is excited or energized.
Having read and seen many interviews of people who remember what they were doing 50 years ago when they heard President John F. Kennedy was assassinated, I suspect the major knots also had a sudden, sharp focus of attention.
Perhaps the chemicals of surprise or fear also help muscles retain knots, as people retain memories of the JFK assassination in more vivid detail than any other days in 1964 or beyond.
Could some knots have a date-and-time stamp?
Sometimes I wonder. I know my massage clients do.
