Taking a little risk

Some days I feel like doing something risky. It's funny how when you get older, you seem to lose that sense of risk-taking. The sense of crazy freedom to just do something wild. Maybe because I am not a laid back kind of gal who likes to hang on the back of used Harleys with a fast driving guy, helmet-free or go skydiving with adrenaline junkies. I am definitely too uptight for that nonsense though still... just once in awhile, I'd like to do something crazy. Maybe a little more crazy than trying out a new eye shadow or leaving dirty dishes in the sink (which I never do). What can I do? What is a little risky and crazy but not totally nuts for someone like me?
