It’s actually push chairs, prams and stollers that got me thinking. I was looking at an advert for a Bob stroller and actually followed the link as “Bob” wasn’t a brand I was aware of. Turns out it’s a “jogging stroller”, again a concept alien to me, but I suppose it may make sense to some people. I’m not a jogger, and if I was one, I don’t think I’d be pushing a pram. But it’s amazing how technology is developed to deal with the specific needs of a certain group of people; or in other words, if there is a market for a product, someone will develop it.
