Thanks all, another year gone and another year of silly adventures to look forward to , this 'getting old' concept is overused. Though the body may degenerate and crock as father time marches relentlessly onward, the mind can remain youthfull (possibly even juvenile ) and continue to dream.
So long as we are able and however unrealistic the future challenge may seem, get to the start line and go ......... and keep going till you can't go any further. It's when you give up trying, is when you have truly given up.
No uranium this time, but plenty more bottles of Scottish 'heavy water'
