I am really bad with temperatures above 26°C, right now its 32°C in the office. At Gran Canaria I was having troubles sleeping and felt oddly fatigued, whilst in Southern Sweden with chilly-mild temperatures in late summer it was really a treat. Well maybe thats also because the air over there was the cleanest air I ever breathed, being in the middle of basicly hectars over hectars of trees and no city pollution.
