Any how, I got sick: constantly picking up the bugs of the 1,000 plus kids I saw a week. Contacted an adult onset asthmatic condition, was lethargic etc etc. Doctors thought the building was “sick”. Administration tested. I would get better in the summer and on long vacations. Finally was forced to take an early retirement, as specialist in Chicago, Cinncinnatti and Louisville all said what ever was causing my condition was killing me. No one thought of lack of sunlight.
Last year, in a week time frame, I ran across three articles on vitamin D deficiency. Check, check, check, check, check.....I had all the symptoms of extreme deficiency. Started taking D, now D3 in gel gradually increasing dose. ...Surprise, surprise I'm healthy for the first time in decades....After all those Dr visits, all that expense, it could have been solved by putting in the sky light I had jokingly asked for for years.
Glad you found the link ...
