This article is about how a single point mutation in the DNA sequence can have an effect on your sleeping patterns. More specifically, your circadian rhythm. The gene with the mutation is CRY1 and this affects the suppressors of the individuals circadian rhythm. This can extend their cycle by at least a half an hour, which can lead to a state of " perpetual jet lag". This isn't an impossible thing to get past though, just requires a stricter sleeping schedule.
My opinion is that this is interesting to learn about, mainly because I am one of these people. On the positive side, it is easier to get past the difficulties if there is enough motivation to get up, like getting something to eat.
