Because 80 million Millenials 18-35 spend 56 hours a week watching Tv, they are always using online on social media, they spend more time shopping than previous generations, and spend more time with friends and family, they actually go to the gym. As a whole, they just don't leave their urban environment. They claim to want to do adventurous stuff like travel, and dangerous things like extreme skiing, sky diving, and mountain climbing, but talk with the marketing crowd that work in those markets and the dollars spent on these claimed activities are missing. Clothes shopping, hi-tech gadgets, cooking, and other urban activities (in-door) are where you will find them. They are 25 percent of the population. We are not the only recreational activity affected by the lack their participation. I'm afraid if it takes more than five minutes to get trained, or you might lose your wireless umbilical cord, you won't see a lot if them coming. The marketing people who study them call them the Enigma Generation.
