  1. Early life experiences can shape physical traits that one might assume are genetic. For example, Japanese soldiers from the northern and southern parts of Japan showed different heat tolerance due to differences in sweat gland innervation patterns influenced by the climate they grew up in, rather than genetics 1.

  2. Iodine is crucial for thyroid health, and most people get sufficient amounts from their diet and table salt. The thyroid combines iodine with the amino acid L-tyrosine to produce thyroid hormones, crucial for metabolism 2.

  4. The developing brain can learn through passive experiences, with neurons being over-connected and eventually undergoing a pruning process to streamline neural pathways. This shaping of the brain continues until about 25 years of age 4.

  5. Taking photos can help enhance memory of an event or experience, even if one never looks at the photos again. The action of taking a photo—or even a mental snapshot—can create a powerful memory aid 5.

  6. Trauma has a significant impact on behavior and the processing of traumatic experiences often involves creating a dissociation from powerful emotions linked to those events 6.

  7. Banksy's art combines two-dimensional art with three-dimensional urban landscapes in a way that brings out concepts and stories, highlighting how our brains encode relationships and interactions between objects to understand complex themes 7.
