Instead of buying a full size cake for my birthday yesterday, friends bought cake pops! Perfect! Gave me the feeling of a treat but a much smaller size and no feeling of deprivation that may have caused me overeat later on a different occasion (we've been there/done that before, right?).
When's the last time you received a tetanus shot? Can't remember, neither could I. I did however turn 40 this past year, so I'm getting one this year so I'll remember I received one during a special birthday year. It doesn't have to be a birthday year, it could be a special anniversary year, high school reunion, child's graduation, just do it in a year that means something. Then when asked by the doctor when was the last time you had one, you should be able to recall.
