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).
How much time that actually is, is astonishing nonetheless: according to Nielsen's Total Audience Report, Americans aged 18 and older spend more than 11 hours a day watching TV, listening to the radio or using smartphones and other electronic devices.
