LCO 112G , please don't concern yourself about my finances I'm more than happy with our financial position wouldn't take advice from anybody at my age, I've come this far and am sitting pretty.
As for being stupid I think you may be very surprised.
I agree.
Premium bonds 'can' give a good return if the investor gets lucky.
Nothing 'stupid' about buying premium bonds as part of a financial package. 
Not quite sure what LCO112G is trying to achieve here. 
I'm perfectly happy with other people buying PB's, since as I've explained ultimately it inflates share prices and therefore increases the returns that I get on my share based assets. It also reduces the taxes I have to pay. I'm just making sure everyone understand that the decision to buy PB's is better for other people than it is for you - unless you win the big prize - which you won't.
I won't invest in things I don't understand, and there are plenty of things I don't understand (VCT's for instance). OEIC/Unit Trust funds are easy to understand, and carry much less risk than single share investing. You don't have to understand share investing to buy funds.
Anyway, if it makes you happy to buy PB's carry on. I've disclosed how you are subsidising me.
