heated towel warmers in each bathroom : )
wearing a yellow vest while cycling (I had gotten lazy about wearing it)
really good cheese on really good bread
hot water bottles
electric kettle
washcloths that are closed on 3 sides like a little mitt (I make my own or buy them in Europe or at IKEA)
added handheld showerheads to both showers in my house
no more top sheet! just a down comforter / duvet
all our cars are manual transmission – oh wait, we already had our cars : ) .... but that makes it easy to rent cars in Europe
front-loading washing machine
drying all laundry except sheets and jeans on a drying rack or clothesline (like we did in the old days!)
I use the 24-hour clock now, and write dates day-month-year (unless it will confuse people!), sometimes in the format using Roman numerals for the month – i.e., today would be 14 VII 2019. Much less confusing (for me!).
.... fun question! I'm sure there are more, as I have lived overseas for a total of more than 8 years. I may keep adding to this list.
OK, a few more: taking my own bags while shopping, long before it became popular here
wearing exclusively natural fibers (cotton, linen)
wearing the same clothes (!!) a few days in a row if it’s not hot
cycling and walking more, as transportation, not as leisure activity
