Tsetse (pronounced /ts/e-/ts/e, teet-SEE, or set-see) are large biting flies from Africa which live by feeding on the blood of vertebrate animals. Tsetse include all the species in the genus Glossina, which are generally placed in their own family, Glossinidae.
Tsetse have been extensively studied because they are biological vectors of the African trypanosomiases, deadly diseases which include sleeping sickness in people and nagana in cattle.
I know there are no tsetse flies where I live but it has been a longstanding source of banter between my sister and I. We love to sleep, there is no denying that. I would take a nap every single day if I could - that after having slept for 10 hours the night before.
Yet these past two weeks, my sleepiness has gone up to a different level. It is just unbelievable! I normally wake up at 8 or 9 in the morning to work on my writing assignments. After lunch I'd then go to work and stay there till 10 or 11. I would even go out to drink and eat from time to time. Yet this week, it has just been hellish! I would wake up at 10 am at the earliest and be very sleepy around 2 or 3 pm. All throughout the day I would just fall asleep intermittently at my desk.
I don't know if I am just starting to get burnt out or if my colleagues are right and I might be pregnant. Which is the lesser of two evils, so to speak?
