If I had GPS in my legs

On the TV at the moment is a combine harvester that doesn't need a human to drive it - it is all automatic based on GPS readings. Quite clever. I actually start to wonder how people could ever navigate before GPS came along. I guess they did it in the same way that people kept crappy diaries before blogs came along.

I was wondering though whether I could have the same technology (the combine harvester not the blog) installed in my actual legs, to help me when I go running. I'd just input a route and then sit back and let the legs do all the work. My brain would be kept free allowing me to spend time composing poetry or admiring wildlife. What fruits might emerge from such an endeavour!

I figure I could also even simplify the route planning process. Rather than having to trace one out on the internet (and again, I ask, how did people know how far they were running before the web?) I could just type in a target distance and the GPS magic machine would plan a route for me, hopefully avoiding the car GPS pitfalls of being told to drive through rivers or fall into pits.

I might even be able to harvest crops along the way.

So if any scientists are reading, you can have this idea for free, dragonden it if you want (and that is a verb, I won't hear anyone say it isn't), just make it happen. Technologise my legs. I'm willing to spend up to 100 English pounds buying it when it's ready so I could become the $200 dollar man! And who says inflation is ever upwards. Just witness the price of series 4 of Buffy on DVD. When it came out several years ago it was about Seventy Quid. Now it's available for around fifteen. Inflation? Pah. Stick Buffy in your basket.
