My experience over the years
 

In progress

I'm going to have to type a little at a time and post to save and continue like that and will remove the in progress once completed. hopefully

Please bare with me, any sort of thinking is one of my major triggers, ex. Dr asks ur age, now my birthdate ok, whats todays date,ok so I'm.....ughh. Brain gets all tinlgy and mushy feeling and start feeling that confussed,scrambled,qwuezy, nauseous feeling and just gets worse from there and always depends oh how hard I have to think.
So what, maybe 2 seconds, if that, of something that is pretty much automatic, hardest thing there is if I know the date and don't even get to the math part.
