In sickness and in more sickness

Haven't been sick for about 6 months, so I guess this is meant to be. I'm thinking of what to blame and found a few options:

1) Melbourne- what the hell is with the weather down there? 16 degrees for summer?!?? Are you kidding me? I guess shivering there for 3 days could have brought on the cold and cough

2) Too much partying over new years. This is less likely the cause for the cold as I drink that much on a normal weekend. Might have something to do with the cough though, the smoke the junk food and the yelling

3) My sister. She's a walking symptom of everything, plus she usually have something to do with my problems =)

4) I'm weakening. This, I refuse to believe!! (and I don't care what you guys say, I'm not in denial)

If something so small can bring me down and piss me off this much, I wonder how those really sick people get on with their days. I admire them
