I am 78 and at that “old man” age where my sleeping pattern has gone thru big changes. I sleep in segments which I have been able to make constant after some time.  This whole series of sleep segments have made my life manageable.  In the past I have struggled with turning off my thoughts by counting, breathing and so on.  Using this sleep tool I now quickly turn off thoughts and relax.  After a short time I have trained my self to fall asleep quickly. Even short naps in the afternoon. This all combines to build up my sleep time to 8 hours total over a 24 hour period. Very effective for me as a retired person. 🤡❤️
That's really cool, John! Thanks for sharing. I hope you aren't doing ONLY naps -- I hope you're getting a core of at least 3 hours in the night time to help you get some deep sleep as well. Deep sleep is super-critical for avoiding Alzheimer's, dementia, etc. as it helps "wash away" proteins that build up and disrupt your brain's ability to function.
