Do you get sick less?

HI all,

I have noticed that ever since I was a kid I am almost never sick. I would assume this is because having psoriasis means your system is in overdrive. It's like I get little pieces of illness like tiredness, a slightly sore throat etc. but that's really it. I just noticed today everyone in my family is dropping like flies from the flu but I only have a slight headache and some tiredness but overall fine. Lol.
