Off my feed

I need to treat myself more like livestock or something. You can tell if something is wrong if they go off their feed.

I haven't been super hungry lately and food has been hard and as it turns out, I'm now sick. Sore throat, funky feeling ears. My younger sib was sick with an ear infection last weekend when I visited so that explains that.  

ugh

Question

 How the frick do people stay warm at mostly empty hockey games. I bring a blanket and hoodie/coat every time and I still end up partially chilly and there are some people here in shorts and tshirts. 

I mean, right now I'm sick, so I understand but I've been to plenty other games and I'm still cold.
