As far as I can make out 'Lifestyle' is a word marketing and other 'trendy, cool and modern' people use to describe the almost endless variety of the stuff we all do as we go about our daily lives. Everything from going to the gym or out for a coffee to sitting at an office desk or working from home.
And in the modern world, it seems to me that the term has been hijacked to use any activity as a marketing tool for fashion or some 'must-have' consumer product. So for my part, welcome to the Brianseye view of people doing stuff.
I've grouped 'Lifestyle' images under several headings - Travel, Special Interest, Physical activities, Ordinary, Luxury, Local event and Leisure.
