Thank you all very much for your welcomes. AWESOME!
What a relief; at first I was afraid of blundering into a no-go area for grandads and of being told to "get lost", or words to that effect. 
Well observed BlueBelle; but no, I hadn't been out on the tiles till 4.00am (see later), and yes, I'm also a night owl. There are many roof solar panels out there with a high risk of electrocution. 
I don't usually lay down my head "perchance to dream" until midnight or beyond. Whenever I'm stumbling around at 4.00am it's not to play with my computer.
But don't mind me; carry on with your naughtiness, I'm shockproof
at my age.
My CV
briefly): I'm an "OBE" aged 90 and a half in fact (note the half; it's very important, to me at least}
.
My better-half, Vera, died Christmas Eve 2015 a few days after our 62nd. wedding anniversary and I'm living alone in our house here in Melbourne, OZ.
That explains the apparent time anomaly BlueBelle; your 4.00am is our 1.00pm, a more civilised lunchtime!
I've spent half my life in the Old Dart and the rest, so far since 1971, here in Melbourne, so I hope I can present a balanced contribution to any discussions.
So, ladies, you can cancel your urgent podiatrist appointments and put those running shoes back under your beds.. [grin[. Sorry to disappoint you; you can't catch me here or lock me in your sheds. Tough! 
If you're still with me thanks for your patience; I could go on about my family etc.: this has made me feel really good; it beats talking to myself even though I'm a very good listener (that must be why Vera loved me so much)
, but there must be a word cap to avoid any boredom. If you insist I'll give you the second thrilling installment later!
Thank you all again, Good Wishes and Good Health

BTW Grumppa thanks for your welcome, but are we the only two grandads in the frame.?
