Thanks friends for your tips on housekeeping, but here is the status.   I will stick to my creative arts and gardening. lol.  Less than a few hours and I quit housework aside from the essentials.

Today's effort:
I cleaned the bathroom, cleaned the kitchen, returned to the bathroom and told someone off, re cleaned bathroom, cleaned bedroom returned and recleaned kitchen recleaned bedroom, recleaned bedroom again, returned the bathroom and kitchen saw it was a mess and returned and recleaned bedroom, happy the lounge room has been a mess all morning. 

I went out and planted 2 pots of dwarf beans, bedroom is still clean because Reg is now settled in the lounge room reading. 
All is good with the world. I looked at Fly lady and decided she is not living with someone with frontal lobe degeneration and I had best stick to household tips from Phyllis Diller and apply a lot of love and humour to the job and be happy to live in a 'Don't invite anyone except your bests friend over', state. :-).

From all this I learned a new way I could try to explain frontal lobe degeneration to my friends.  When they see my husband they see a normal adult, a beautiful man, which he is.  The thing is he cannot plan more than one step ahead. To him the towel r the apple at the bottom of the pile is identical to the one at the top and if you want it you just reach for it and pull….. 

Now Phyllis Diller’s trick of swishing that all into a corner and throwing a rug over it, arranging a bowl of flowers in front of the covered mess and  sticking an easel up in the middle of the room so people will say ‘you are artistic’, sounds good to me.  No I am not going to try to ‘stay on top of it’, lol, I will read through fly lady and see if there is anything there that is useful, maybe there is a chapter in there on dealing with autism or dementia, housework under the circumstances of being a carer for someone with an illness of the brain is not exactly the same as just  being a housekeeper.
