Grant owned one slave in his life, William Jones, whom he set free in 1859. Julia had the use of four of her father's slaves. These slaves were all free by 1863. In 1864, the Grants hired one of those former slaves, whose name was also Julia, as a paid nurse.
The data shows that 18-to-24-year-olds â generally college students and new entrants into the work force â watch the smallest amount of live TV of any age group (three and a half hours a day), spend the most time text messaging (29 minutes a day) and watch the most online video (5.5 minutes a day).
In fact, research suggests people between the ages of 18 and 34 watch more than two hours of Internet or mobile video per week, in addition to the average 23 hours they spend tuned into live TV.
