Well apparently it does technically change. according to my dad at first they mess with your shed (I have experience of this), but on the other side you get 'Benefits' (only very limited experience of this as I wasnt prepared to have my bench messed with as well) if you let them mess the shed up. BUT once the shed and bench are messed up and you have to spend your cash on food and kids (like my dad) then things get much worse because apparently they stop or at least ration the 'benefits', now I admit the last bit is anecdotal and outside my experience but my dad is a fairly reliable source. I can also confirm he is skint and has to borrow from my parts store (reduced rates seeing as most of it started life in his shed), so yeah I guess it does change but not for the better.
Girls were interesting for a while but science is less hassle and not once have I had a resistor object to being desoldered in favor of a better resistor! I cant say the same when I found a more suitable GF, the previous one wasnt happy at all
