|People with OCD need to repeat ideas or actions,
which don't make sense, but the need to do
it is very strong. The most common example is
washing your hands a hundred times a day.
A mild example would be the one we used to do as
kids: "Step on a crack, break somebody's back."
We grew out of it. Another mild one is checking
a zillion times whether you turned off the stove.
If you find this sort of thing continuing for too long,
it's best to see a doctor or therapist about it.
Severe OCD can take over
your life and become disabling.
