So-called "senior moments" are becoming increasingly common among younger people, recent data has found, and it's thought to be due, at least in part, to excessive reliance on technology. A 2013 Trending Machine national poll found that millennials (aged 18-34) are more likely than those over the age of 55 to forget what day it is (15 percent vs. 7 percent) and where they put their keys (14 percent vs. 8 percent). Gen-Yers even forget to take a shower (6 percent) more frequently than seniors. Rising stress levels (which may also have something to do with constant connectivity) could be a factor as well.
