Remember the VAT rate when you hit 50

Not to everyone's style and too late for me but when you hit age fifty you could claim:

"I'm not 50, I'm 43 plus VAT"

When VAT goes back up to 17.5%, 50 yr olds will be 42 plus VAT!

I suppose you could try a similar approach if caught speeding at anything upto 15% above the limit, but I wouldn't recommend it!
