Does anyone ever notice a nervous tension around the place? The happy faces and sunburned faces belie a sadness IMO. Ultimately while we can enjoy it we know it is short lived and so there always seems to be a bit of tension when we get a heat wave. The sun obviously makes everyone more extroverted but we're not psychologically prepped to deal with it. We haven't evolved for good weather at all, whatever about physiologically,mentally it just isn't what we are adapted to.
