Its a pot of magic.   If you cannot get around much anymore and find that you have to sit in a position for far too long, to make sure you do not get a bed sore or similar, just rub in some vaseline.    Its wonderful stuff, prevents you from chaffing.   People who are plump with maybe a few extra rolls of flesh, once you have had your shower just smear some vaseline in the spots where the flesh meets.    Best of all you can buy a huge pot of vaseline from such shops as poundland for £1.00.    Instead of going to the doctor when you have a problem, prevent it with vaseline....and no I do not have shares in the product.
