Time managment and focus

I am certain this question has been answered in several episodes but I am curious about a statistic that I have read in some time management articles. I ascribe to your information about circadian rythms, exposure to sunlight, sleep cycles, and more. I have become much more productive and satisfied by applying information that I've learned here. I have read a statistic in several articles by other authors: "It takes about 23 minutes to get back into a state of flow" when distracted or pulled into other things mid-task. Is this true? I also have read as people age it can take longer--I am 62 and have noticed that it takes me longer to return to a task or even remember where I left off. I would love to harness this information to use to change some of the work processes at my job. There is an expectation in my work environment that Microsoft Teams and Outlook are to be attended to throughout the day, which I think is detrimental to productivity. I also think Teams is now "overused" in the work ennvironmennt as a way to share information. It is impossible to respond to all the data that is being shared by so many people. It would be better if the organization instituted a better way to use Teams and Outlook--like allowing for Teams/Outlook-free chunks of time. I'm saying this because for every email or teams message that needs prompt attention, it prolongs whatever task I am working on. Sometimes it takes me all day to get something done because I've been interrupted so much. I loved Dr. Kay Tye's method of addressing email! I felt very validated, because I decided I can't make other people's emails my priority. There are other ways to impart important information. And quite frankly, I believe that it is not possible to get everythihg done. I have come to accept that not everything will be done or done perfectly. So I guess my question is: Is this widely quoted statistic correct? Does it take about 23 minutes to return to flow after a distraction? And could you do a podcast about time management? I know that the answers about attention, focus and the best ways to schedule tasks can be found in podcasts about brain health, dopamine, attention and focus. Can you do a podcast from the perspective of time management? Thank you. I realize that a lot of this information can be found in several episodes. I love you podcast series, which is why I'm a subscriber.

Efficacy of chiropractor techniques

Can you do an episode on the general field of chiropractors? For me this question derives from my wife having Meniere's Disease and finding some compelling indications of the value of upper cervical (atlas) realignment. At the same time I was taught early in life to mistrust the chiropractor industry. I can't help hoping this is a bit like acupuncture. Misunderstood. Some number of quacks. But perhaps a valid basis underneath?

Tyrosine supplementation increases appetite.

I'm ADHD and otherwise unmedicated until my perimenopause settles down along with other untoward side effects (Vyvanse induced hypertension). I've been trialling Tyrosine and it does seem to have some effect on perceived stress and is making a mundane work choice bearable. It doesn't however help with studying as it makes me quite sleepy, but more interestingly, it makes me very hungry! It almost feels like it lessens my already low impulse control as I find myself continually reaching for something to eat and unable to stop myself. I'm aware of some research done in anorexic mice but as a healthy weight female human I'm just wondering what may be happening to cause such an increase in appetite.

Does too much sleep cause depression?

My experience is that when I sleep a lot (more than 8 hours) I start to feel really down/heavy/bad thoughts. I know how much you stress getting enough sleep, but is there anything you can speak to about too much sleep? I realize this might be a chicken-egg thing - maybe the reason I've been wanting to sleep more is the lack of motivation/drive that causes the heaviness. But have always been curious about this relationship. Perhaps a better question is: What happens to the brain when we sleep more than 8 hours? Thank you for your interest in humanity Dr Huberman!
