This winter has been long - not a big issue for me and one of the best winters I've had in a long time. I normally get SAD - read here In recent years I took St Johns Wort - basically a herbal antidepressant. Thankfully I have never had petrochemical anti depressants. I understand they come with side effects St John's wort does not other than like most medicines it has to be removed from the system slowly so as the weather warmed and the days got longer I cut the tablet up in halves then quarters !
This year I have not needed it - I attribute that to more daylight, more exercise and more fresh air - walking and seeing daylight rather than being cooped up in an office or office buildings. +1 for retirement.
Anyhow for the record we jumped on the extra hour gained when the clocks went forward and took a late evening 5 miler around Bosham and Chichester harbour. We were rewarded with still tranquility, isolation and a beautiful sunset. I do not have the words but do have the pictures.
