Is this the beginning of dementia?

I feel that I need to set out my lapses before I don't even know I am having lapses.  While once I put my drivers licence into the ATM (by the way that does not work) my lack of concentration is growing more and more pronounced.  Lately, I have tried to answer a drink of water instead of answering the phone.  In my defence the phone had awakened me from a deep sleep so grabbing my glass of water may or may not be justifiable.

Nowadays I get easily distracted.  I tend to put the frying pan on to heat up and then forget it.  In fact I actually need to stick to doing one thing at a time.  No more putting something away in another room and then forgetting the task in hand to making the bed or perhaps putting out the re-cycling.  Once I have done the re-cycling I water the plants or do a bit of weeding.  Needless to say by the time I come back in smoke is billowing from an extremely hot frying pan.  I also think that if I am making scones I should stay in the kitchen and not make crispy nuggets.

Last night I excelled myself.  I rang a friend and then got caught up in something on the television. Eventually I noticed that I was holding the phone in my hand and remembered that I was supposed to be talking to my friend, who in the meantime had hung up.  I wonder if she thought is was one of those prank calls.  I rang her again and confessed my inattention.

When I was younger the silly things that oldies do was amusing.  Now that I am 67 and thence on downhill  run to 70, the story is not so funny.  I don't want to be the silly senile oldie that my friends giggle about. I don't want to lose it; in particular my ability to function in day to day life.  Inside I am 23 and outside I look pretty wrinkly and that I don't mind but losing my mind is a bit of a worry.

PS Today I finished a phone call but was still cradling the phone on my shoulder some time later while I was cleaning the bathroom.  Whoops.

PPS While making toast I somehow put a tea towel on the top of the toaster and made smoke rather than toast.  What is going on in my tiny brain.  Not much I suppose.
