Why are my colds so severe?

I have the same problem.I am now 46 and I have found the older you get you do not get as sick as much.Also when you first feel a cold coming on try zinc.It works for me.But you have to take it the first two days of a cold and your cold will go away.Also start taking vitamin c now.You can also drink lots of juice.I have been to the Dr and he put me on flonase It is a nose spray but I did not take it like I should so I can not say if it would of helped me or not.
