sickness and birthdays

Why do birthdays and sickness happen around the same time?
i haven't posted in a while because I've been sick and i was in Oregon.
Well now I'm officially 13 and so is bluebyrd and also today is yellowbyrds birthday.
I was better yesterday but this morning i was sick again.I hate being sick cause all i do is lie in bed and i keep forgetting how it is to feel sick and its very annoying.Anyway Oregon was fun besides getting sick but to the point i went to see my cousins.
Happy birthday to all of you out there!
