Does it affect the realities of others? Well, obviously, if it meant, that you can control others, it would disprove itself right away. It would imply that they did not have the same control over their experience.
The interesting part is the one regarding the base reality. What is our base reality? If we look to the outside and its phenomena we are like the ones that mistake the shadows on the wall for the real thing. In a dream we readily acknowledge that it is “just a dream”. In this waking reality, however, most will fight nail and tooth to defend their experience, their shadows on the wall, as being “real”.
“Currently we do not have anyone who has a photographic memory in the world.” Strong claim. Probably not true. More interestingly, why would you want to believe something like this?
“it is because of the conscious belief that this isn’t going to be acquired in this way at this time that there is a lack of it existing” - “Man will never be able to fly. - If man was meant to fly, God would have given him wings.” How long ago did people believe that and what does our reality now include? Airplanes, spacecraft, people in batman suits that fly through canyons.
Just because we have not observed a certain phenomena yet, does not mean that it does not exist or that it won’t exist in the future.
Yes, I think the sole purpose of the brain is to give you limiters so that we can have this imaginary experience. Most people that seem to have a photographic memory are idiot savants. I am not saying that having a photographic memory is necessarily bad but currently it would be a challenge for most people to make use of all the data that would be available to them. Until we know what our “base reality” is, a photographic memory is probably the least thing we should wish for.
I haven’t watched the video so I’m not sure about the context, but there have been human studies on fasting.
I’ve experimented with intermittent fasting and water fasting for years. I can only give anecdotal stories, but I found it surprisingly beneficial for my health condition.
I do seven days from time to time and it clears my mind like meditation. Feels great physically too. I find it to breathtakingly effective. I can’t believe I’ve discovered fasting a bit over 20 years ago ! Amazing how it goes " fast " !
it is so very very hard at first, but when done well and enough time to understand one own body in relation to it, gets easier fast, like memory techniques 
Nice, the longest I’ve gone is 5 days (water only), but I’d like to do a longer one. I can’t say that I enjoy it, but it suppresses my symptoms a lot by the time I’m done. The best I’ve felt with it was when I did alternate day eating (eating during 24 hours, then not eating for 24 hours, switching at 4pm daily), but there were other side effects so I had to stop it.
the first two three days are the worst for me, so I know I just have to get past that. when I started out I had a light cheating trick to pass through those couple first days, it was to heat up some vegetable broth yark at first, so yummy yummy when hungry! Ok, sorry for being off topic a bit, cheers all!
I tried to make my not eating window longer by skipping breakfast, but I felt really bad in the morning. Maybe after let say 24 hours things may change, like your body gets in a different state.
