Coffee

I used to hate coffee as it tasted like cigarettes. However, ever since my MBA, I started to like this drink. Waking up at around 8am for class on a weekend is something unusual for me due to my working hours. I felt sleepy during the class in the morning and occasionally dozed off. ITD provides free coffee and it effectively kept me awake. Even though it’s not some premium coffee, I started to like it, taking it whenever I felt sleepy. Is this a sign of aging?
