I joined a new support group recently for people trying dieting, and I met two people my first day who were really nice to me. One was pretty heavy and the other was really thin. The next week that I went to the dieting support group, though, I only saw the pretty heavy person, and was later told that the really thin one had decided to leave the group since they didn't want to diet anymore. Question: Who gave up on their diet?

Technology is advancing with a startling pace, and some people have trouble keeping up with the most modern aspects. A recent interview with a retiree and a middle school student aimed to get at just this issue. Only one of the two had difficulties, though. The retiree found that they actually enjoyed adapting to the newest thing, and it was only the middle school student who found the whole processing too exhausting, and kind of gave up completely already. Question: Who is up to date with modern times?
