The line graphs depict changes in the percentage of electrical appliances owned by households in a country and how many hours per week people spent doing chores inside their homes from 1920 to 2019, a 99-year period.
Overall, the percentage of households with electrical appliances increased, while the number of hours allocated to housework plummeted over the period.
With regards to owning electrical appliances, almost nobody possessed a refrigerator in 1920, while in 1980 there was a fridge in every single home, which remained unchanged for the rest of the period. The figures for washing machine and vacuum cleaner stood at 40 and 30 percent respectively at the beginning of the period. These percentages rose over the next 40 years and reached 60. Over the remainder of the period, the figure for vacuum cleaner saw a sharp increase to reach a high of 100 percent, but the one for washing machine reached just over 70 percent in the final year.
Regarding the number of hours per week spent doing house chores, the figure stood at 50 in the first year. This number declined steadily over the 99 years to hit a trough of 10 hours.

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
