psychology studies? Post a stupid question, see who responds and then
analyse the results? Seen it all before, they all appear at the same time
each year together with the "help me to design" requests.

Stop being such a tedious miseryguts.

He's made the first critical step, which is admitting he doesn't know and
needs to ask somebody.

For the OP : get hold of a copy of a decent DIY book - IIRC the Collins one
is quite good. A library may well have one.
