Terrible Math Skills
Math is a challenging subject to study. However, if you are aware that you are not particularly skilled at it, that is perfectly acceptable. Worse than those who have poor math skills themselves are those who are proud of how bad they are at the subject. Naturally, we don’t even have a clue how people can be so good at mathematics.
If you take the person’s current age and add eight to the year in which they were born, you will arrive at the age of eighteen, correct? That makes absolutely no sense in any way, shape, or form. Wait a minute. Even if you wanted this to be a loophole, there is no way it can be used in that way because it doesn’t work out at all!
