Are you using the definition of "100+ years old" for antique, Kev?
Have to say, I do like it. I like Mark doing anything, but I'm biased.
I believe he is trying to promote the whole idea of buying second-hand stuff - it's recycling, it's "green" and it's economical - and you can end up with things of far superior quality.
(he has an article on how "green" antiques and collectables are on his Blog)
It IS a lifestyle thing, and it's a stark contrast to the current "disposable" lifestyle, where every new thing you buy needs thrown out within a year or so!
I also find it useful to be aware of the "current popular knowledge" about stuff, and this sort of programme is where the public (- whoops, nearly said plebs
) get their info!
