How to get uptime history?

I can get uptime from uptime but what about time between boot and shutdown historically?

If the last part was the duration (days+hour:minutes), it doesn't make sense that time between reboot is overlapped

uptime
 04:32:34 up 7 days,  1:45,  6 users,  load average: 0.72, 1.80, 2.43
last -F | grep -i boot
reboot   system boot  6.0.12-76060006- Wed Feb 15 10:49:34 2023 - Thu Feb 16 23:37:21 2023 (1+12:47)

Rather than trying to squeeze this juice out of `uptime`, use `journalctl`. Read `man journalctl`. `sudo journalctl --list-boots`, then for each boot number, `sudo journalctl -b #` will show the beginning of the log, and `sudo journalctl -b # -e` will show the end.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
