I still have the bottle of Aztec Purple nail polish I was given, 35 years ago, to paint my toenails. It matched the purple corduroy flared jeans I wore with my lilac shirt. And I was stone cold sober.

Thank goodness the 70s are now a very distant memory.

Even though they reckon I have no discernable" style" my daughters can't believe I was so uncool.

But I still use the nail polish as "poor man's Loctite" and it stops all the little screws and nuts in gear that must be frequently moved from unscrewing themselves. And its colour means I can see which ones I've missed.

Cheers, Rowan
