How to give yourself myocardial infarction

It's really simple. Frighteningly simple! Just go home on your merry way, pick up your bag and head out to the supermarket. Walk in the door of the supermarket and realise 'oh crap, my wallet has gone', and spend a panicked five minutes before you realise you've left it at work. And have to go back to get it.

My own idiocy amazes me. I'd have a far less stressful life if I wasnt so distracted! Good news being that I'm getting more money in as my salary than I thought (tax less than expected), but this is without saving anything: have to start putting some by at some point!
