Why does handwriting change so much and so frequently?

Why does our handwriting change?

• I'm curious about why our handwriting changes throughout the course of a day (or some period of time). For instance, today morning my handwriting was larger and messier, later in the day the letters were smaller and neater. I wasn't purposely trying to make my handwriting neater, it just came out that way naturally. Additionally, sometimes I naturally begin to write in script, why does this happen? I usually don't make a conscious decision to write in script...it just happens. I realize that the type of pen/pencil you use could affect this, but could the difference in handwriting indicate some subconscious change in mood? Wouldn't this make it difficult to identify a person's work if the handwriting style changes from time to time?

• Answer:

  Maybe you were tired this morning? I mean sometimes my handwriting is horrible. Just a guess tho.
