Older and wiser? Aye right!

I've been laid up all week with a sporting injury...well I suppose that tripping and rugby tackling a cast iron litter bin, whilst running for a taxi, after watching a six nations match in the pub strictly speaking isn't a sporting injury, but hey gie's a break.
A break is what I nearly gave myself anyway, a broken shoulder that is, and a dunt on the head into the bargain.
My left arm has been out of action all week, it's coming back into use now but only slowly and painfully.
Odd thing is that since my head bump both tea and coffee are tasting strange.
I've only had one cup and a couple of exploratory sips of each all week.
Now I don't know whether the headaches are bin-bang related or caffeine withdrawl symptoms.
So what's going on? Either the knock on the nogging has effected the way interpret certain tastes or there's something up with our water that because I've been off work I don't know about. I know which I'd bet on.
It was my birthday too, and I'd had a nice weekend up until that point.
Since my age is now the answer to the great question of Life, the Universe and Everything I'm hoping that at the very least I've gained a few nuggets new wisdom through the experience;
1. Taxi's aren't like other forms of public transport, they don't leave without their passengers coz if they do they don't get paid.
2. "Mostly 'armless" jokes just aren't really that funny.
and
3. Scotland should consider fielding a couple of cast iron litter bins against England in the next six nations match. They're bloody hard to bring down!

Only time will tell whether I've knocked some sense into myself or lost what little I had.
After reading this you may have already formed your own concussion, sorry conclusion on that one.
