In the past three months, I've had 2 colds. This isn't very normal for me, as I usually get 2 a year, but several months apart. The colds aren't that severe, but I'm worried that my immune system isn't as strong as it used to be or should be because these colds have only been a max of 2-3 months apart. Does anyone have any thoughts on this. As always, any input is greatly appreciated.
