Must be time for another "Rule for Life"

This is, I would have thought, an obvious one, even though I know it is routinely breached in the name of fitness.   And it sprung to mind because of this story: 

The day after I wrote in the Guardian about how my life as a female cyclist, and Paralympian, led to me having reconstructive surgery of my vulva – all because saddles are not designed for women – a book arrived in the post.

The rule:

*  If an activity hurts a lot and causes inflammation - stop doing it.  Permanently, if it keeps hurting.

What am I up to?  6?

1.  Always carry a clean, ironed handkerchief in your pocket.  Always.
2.  Never buy into timeshare apartments or holiday schemes.
3.  If you have a choice, buy the washing machine with a 15 minute "fast wash" option.
4.  Always buy reverseable belts. (You know, usually black on one side and brown on the other.)
5.  The best souvenir when on a good holiday is a distinctive cup or mug, which is to be used semi-regularly on your return.  (Don't get in the rut of using the same mug daily for years - you need to rotate through all of them.)  Use will prompt good memories and make you happier. 
6.  If an activity hurts a lot and causes inflammation - stop doing it.  Permanently, if it keeps hurting.

Just reviewing some of my past posts, I think I thought about adding another, but never officially did.  It's good and valid, though:

7.  If a potential boyfriend or girlfriend says, with intended irony, that they know that they can be a bit of a creep (or difficult) - don't believe the irony.   Just don't get into a relationship of any kind with them.
