It would be interesting to see those with quite poignent bits of advice to then add the why? to it.
I'm interest to hear what happened to the guy who lept the 2ft wall to falldown 20ft the other side.
Or the advice NOT to ride the motorcyle on the 2nd day of fence painting.
As for me......."do not clean Darren's SLR mags with his bayonet (just because he is using the proper tool). It has brasso on it....and is gonna change your life"
Reason: In 1987, i got a mahoosive infection from above mistake, ended up being MD'd from Royal Marines, 9 years too early.
