Imparnumerophobia

Imparnumerophobia (from Latin impar, "odd", and numerus, "number") is the fear of odd numbers. Imparnumerophobes would make sure everything they do is even, like the amount of foods eaten. Some sufferers may bear less of the odd numbers whose sum of the digits is an even number, like 13 (1+3=4), than odd numbers that sum up to odd number, like 25 (2+5=7). Few sufferers may not unbear odd numbers divisible by a certain number, like by 3 or 5.
