A point of interest from my own medical history, which I got reminded of today by experiencing it again: having dizziness associated with changing positions from laying down to sitting to standing is because your blood pressure drops when you change positions, which is called orthostatic vitals, which in my own personal case, is caused by being a little dehydrated and usually by not having my customary dose of caffeine in my system. That is, this morning I didn't have my customary three cups of cola and I nearly passed out while cleaning up at work.
My special snowflake for today is my cat. Despite have free access to and from the outside from the back of my house, she prefers to wait in the front of the house and meow until I let her in - even though she went out the back.
