It's not the individual case I'm griping about. What concerns me is the tendency to only follow the rules that suit you. Lots of people do it, and whilst at one end of the spectrum it is people flocking to beauty spots, at the other end it is flocking to raves under motorway flyovers. Two sides of a similar coin for me.
I'd love to go walking every day, it used to be a big part of my daily routine. But the parks are full of joggers panting all over everyone they pass these days and it doesn't feel like it is worth the risk. Let's face it, if I'm ill, it affects a lot more people than just me.
