What is Alzheimer’s Disease and what causes it? In this video designed for elementary learning we explore those questions and help gain a deeper understanding of this disease. Many of us know someone who has been affected by dementia or Alzheimers and if not many of us might in the future. We hope this video helps students gain a better understanding of the disease, its causes, symptoms, and some prevention techniques.
Alzheimer’s Disease is a type of dementia that causes problems with memory, thinking, and behavior. Dementia is a set of symptoms that may include memory loss and difficulties with thinking, problem-solving, or language. Alzheimer’s Disease is the most common cause of dementia.
Alzheimer’s Symptoms: As a person ages, they may forget things. It is normal. However, one of the symptoms of AD is consistent memory loss, especially of recent events and new information. This is the most noticeable trait of Alzheimer’s, it usually occurs gradually at first, but gets worse over time.
Alzheimer’s Prevention Ideas: As you learn, your brain is constantly making connections, and one way that might help prevent Alzheimer’s as you get older is to produce new connections. You can do this by staying active, mentally and physically. This also apples to adult family members or friends who do not have AD. Encourage them to be active too.

Watch my interview with Meredith on Nebula (get 50% with my link): https://go.nebula.tv/simonclark
Before engaging in his second oil war of Q1 2026, President Trump took his most harmful act to date against climate action. In this video we talk about what that was, why the people fighting him are probably going to win, and why the whole thing could backfire in a big way for Trump and his oily glucose guardians.

For many of us in the West, aviation is a huge chunk of our climate impact, and most of the impact of any given flight doesn’t even come from its carbon emissions. Fortunately, new analysis and field tests indicate that this impact can be mitigated quickly, cheaply, and safely.
If you wanted a message to send to your airline, perhaps something like the following?
“Hello [AIRLINE], I am one of your customers. Do you incorporate contrail avoidance into your flight routing or are you planning to take part in one of the many trials in contrail avoidance? Here’s a website explaining how easy and effective it is: contrails.org”.
