Is it because of the hours I work?
Is it because I don't exercise enough?
Is it because of my bad diet or sweet tooth?
Its all because I'm what's known as a short sleeper.
Because I sleep less than average then I eat more so I put more weight on despite using on average 1,000 more calories per day than a long sleeper.
And its true because a scientist says so, so now I know why I'm fat!
