    One time I was lying in bed with my six-year-old daughter trying to help her fall asleep. I was trying to teach her mindfulness so I told her to lie quietly and be mindful of how each toe felt. We practiced that silently together and I must have been pretty tired because all of a sudden I found myself hallucinating that each of my toes had money and they were going to go buy things. It was bizarre. My daughter and I still giggle about this memory 😂

    Sounds like fishing to support a social theory. There will be genetic aberrations that doesn't mean that they're a normal part of genetics "spectrum characteristics". Cancer is quite often due to genetic factors, but we don't consider them part of the normal "spectrum". These specific things mentioned in the video have little to do with current debates on biological sex. It seems to me that statistical genetic outliers to prop up a social argument. If you were born with a 23rd pair consisting of XY pairing in normal fallowing anatomical physical progression, you are a male, and vice versa for a female. Feelings have little to do with physical reality. I can "feeeelll" all I want that the Moon is made of cheese, fairies are real, and the Earth is flat.... However, feeling all that doesn't make it so.

    Its seems logical to me that elephants would forage farther if storms were coming. It would be much easier physically to travel longer distances during cooler wet conditions than hot and dry ones. Plus the elephant may also reason its not as dangerous to stray farther from known reliable water sources when wet conditions are coming. Seems self evident but thats just me so...???

    I think that this could be a huge issue that will make health problems that must be addressed many years before an illness will or will not occur. Imagine being a child that is told to take medical treatment for that future illness. Let me guess that it will take some mental toll on the normal development that is expected. This will result in huge impact for the rest of this child. This is just one aspect of many that must be considered before. It's not all good and I expect your channel to be realistic and present the benefits and the dangers of implementing such a radical change in health care.

    Conventional growing is not farming, but mining. Growers are slowly mining out the soil fertility, with diminishing returns. Chemical corps started selling them on quick fixes in the 1920s. The more they used, the more they needed, and when they were hooked, the prices stared to slowly go up. Small farms started to go broke and larger ones formed, turned into corps, heavily financed by banks who controlled operations with lending conditions, e.g., use of chemicals, machinery. Govt. regs helped increase the control. The propaganda claims this to be "modern farming" that is feeding the world. It isn't. It is a catastrophic failure. Meanwhile, some farmers are opting out, using no chemicals, growing more produce with less overhead, e.g., no-till, crop rotation, companion growing, based on a philosophy of working with nature, not against it as if it were the enemy, as the corps had taught. This was named "organic" at first, but as it developed it is calling itself "natural".

    When I was a kid, my older brother managed to convince me of a remarkably similar explanation of elephant communication over great dices, his version attracting additional credibility by accounting for an elephant's unusually large ears and nose (trunk). Translated from 7 yr old to Adult, he said, "When too far apart to hear trumpeting calls, elephants use infrasonic flatulence to communicate." Worked for me.

    I can't remember where I have seen was some kind of documentary, where they tested a device which sends out this mating call and the elephants came quickly after the message was sent out. The interesting part was that this communication happened via the ground, so the sound was channeled into the ground, travelled there and was picked up by another elephant through its legs from the ground.
