Seriously? Here in the UK? You gotta be kidding me!
But here's a man, Mark Boyle, who's been living freeconomic lifestyle for a couple of years now. There's a yahoo group which used to be called freecycle but is now changed to freegle where people give away their unwanted stuff and it's where he got a caravan for a house for and he parks it in a farm for free in exchange of his labour. I for one have gotten loads of free stuff from the site, from TV to bed, tables and chairs, plants, and even a piano if I wanted to but I don't have a space in my house. Furthermore, He gets around on his bike and he plants his or barter for food. He goes on a holiday and sleep in other people's couches for free accommodation. The internet is a fantastic place to find free stuff.
Seriously, living a life like that is a remarkable feat, I must say, especially if you live in the UK. This is home for Mark Boyle and so there is no need to pay for visa for example. But I believe that what he is trying to prove is that money is not a necessity for existence. I have heard time and again people say that "the best things in life are free". I concur to this. People work for money chasing their dreams or even a mere want. But in real essence they only provide transient satisfaction. When you can't sleep at night, your gadgets can't help--that sort of thing. I could ramble on and on but I think it's better to let your sound judgement on the matter come to play.
