How many times do you clear out your medicine cabinet? It has been a while since I have done it, but if I remember I try to check the date on medicines before I take them. However, I have found the odd box of painkillers, vitamin tablets and indigestion remedies out of date lingering in the cupboard. This probably means that I have taken the odd out-of-date medicine, but I am still here to tell the tale. It's easy to do if you are in pain or have just remembered to take your medication. But have you made a similar mistake?
