That would be me. I only realised how ingrained some of my habits are in the last 6 months or so, and it was in large part thanks to my doctor.
I have to have (at least) annual blood tests to check my kidney function, and at least once a year my Vitamin B & D levels, as well as cholesterol, white cell count and other stuff is checked. At my last check, everything was fine, except my Vitamin D, that was down to 38 (normal is 50+) and my white cell count was also down.
After some discussion, we hit on the issue for at least the Vitamin D - sunscreen. I have worn sunscreen and sunglasses religiously 365 days a year for more than 2 decades, and this has driven my levels of Vitamin D down over winter. Trying to not wear sunscreen for the first 15 minutes of the day, and going outside sans sunscreen for that time nearly drove me bonkers, so ingrained was the routine. Last test was fine, back to 58. I was still wearing sunscreen all the time (I gave up trying to beat the habit) but it was summer, and I was spending more time in the sun. The white cell count was, we decided, just an anomoly, it tends to drop in winter (a pattern of many years).
The force of habit was further brought home to me the other night, I stepped out of the motorhome in the dark, and stepped into my 'camp' shoes, which were sitting in the exact spot where I always leave them. Sheldon pointed out that I didn't even look, I just put them on. Again, habit.
This got me thinking about how routinesed human beings are; we take the same routes to destinations we visit regularly, we run particular errands on specific days, we eat at the same place time and again (guilty, Thai Imperial Palace), we drink a specific drink, or stick within a specific list (skinny latte, skinny hot chocolate, no marshmallows, or skinny chai latte), or have a cigarette with coffee or alcohol.
I have become less inclined to do particular things on particular days since we got the MH, but certain habits still hold on (shoes, sunglasses & sunscreen being 3). But, if those, and my preference of restaurant in Devonport, choice of footwear to purchase (flats) and preference of hot beverages are the worst habits I have, then I guess I am ok. I just need to get exercise andhair/ makup into my habits, and I will be set for life!
