Given that a day has 86400 seconds, and we spend around 57600 seconds awake and 56340 seconds according to one credible source (Statisca claims: "This statistic displays information on the amount of time individuals spent awake per day in the United Kingdom (UK) in 2014, broken down by age group and gender. That year, the average awake time for UK adults aged 16 years and older was 939 minutes or 15 hours and 39 minutes. A recent study on media and communications usage in the UK shows that the average awake time of adults remained largely unchanged two years later in 2016, at 940 minutes. In 2014, the average UK male spent 11 minutes longer being awake than the average female, at 945 minutes and 934 minutes respectively.
A 2016 survey found that UK adults aged 16 years and older spent roughly 525 minutes, or nearly 56 percent, of their daily awake time on media and communications activities, such as watching television and videos, listening to the radio or music and communicating via email or instant messengers."). So with the fact that we use half our time using electronics in United Kingdom specifically that means it the number varies from person to person, if you are in Afghanistan for example, you wouldn't use a lot electronics devices and enjoy with friends and familly time. So I conclude, it would be hard to reach 100,000 words per day, unless you watch videos all day.
