Talking of people suffering sadness/tiredness from the lack of light, there is a growing number of people in the UK saying they are suffering 'Seasonal affective order' every winter when it becomes dark, i've never had it however, i've worked outside all the time, i go out on the weekends into the forests and mountains, i feel that because the more modern world is in a 'live for the summer/party all the time' that people are seeing winter as an unnecessary season in a way, if that makes sense, young people here wait for the sun as a queue to drink and stay up with the longer sunlight and the warmth, but soon beg for 'abit of rain' then when the season changes its back to the 'omg i hate rain...when will the summer be back, theres nothing to do blah blah'

I think I started to rant a little there aha sorry.
