procrastination, theres an old phrase which says why put off til tomorrow what you can put off til next week, i suspect theres something in me which doesnt like being assessed marked and criticised, which is what happens when work gets assessed, so a combination of procrastination and not wanting to be assesed,so brain turns off and other things come to mind, but there is something strange with my memory, things i know inside and out suddenly become fluffy vague things, brain turns off and things sit there taunting me just out of reach, its a pain in the bum at times when you know something well and you cant remember what it is but have a shape there which tells you what it is about, sometimes my memory just doesnt work, i forget words sometimes for no reason, its quite embarressing pulling up on a motorbike, then talking to someone and forgetting the word motorbike! it makes talking about such things most difficult, brain turns of at inconvenient times, and seems to enjoy doing so when i have work to do, will figure it out someday
