for me yesterday was such a day. I woke up with it , but still wanted to try and carry on. First attempt to start the chainsaw in the morning saw me "wobble and sit down" when I bent over to pull cord.
but I note with interest your comment on low blood pressure. I then ate a chocolate and berry muffin and strong coffee which enabled me to stumble through rest of day. Including some sawing .Still was woosy on and off throughout but I survived. I really wanted to get a few things done.
I'm on my hands and knees for a fair part of day doing decking and it's this sort of work with head down that can kick it off within a day or so.
