Ahh, we all that know feeling Noz!
Muscle hangovers, beer hangovers, we know it all!
Don't take much for me to have this muscle ache, because I am a very lazy person. But the funny part is, when my mind is tired, my body gets like this as well - last sunday I had to work on the elections here in Brazil and I could barely walk, which is weird because I spent the whole day sitting.... but my mind wouldn't know the difference between physical and mental effort.
Yeah, it's weird, I could easily sit doing office work for the entire day, then get on the train and FIGHT for a seat. As if I haven't been sitting enough for the day? Bodies are weird. And stupid. Sometimes.
