I spend £30 on mine. I know you can buy cheaper but the way I see it is work is mostly a pain which you'd rather not be doing. It's stressful, dull, physically demanding and often quite lonesome. I like to take measures to cheer myself up. It's the little things. Having some sweets to suck on while driving, download some interesting podcasts to listen to. Wearing something that I feel I look half decent in is just another thing you can do. Pride in your appearance makes you feel better. If you're properly groomed and looking ok it subtly lifts your mood - just like, conversley, wearing cheap tat makes you feel like cheap tat. We're all vain to some extent, some of us just choose to revel in it. But when I'm 50 I doubt I'll bother. While I'm still a lean, mean, bubbling sex-machine it would be an injustice not to tart myself up a smidge. Just think of the ladies!
