I trust you're safe, fit and well.

All strength to Ukraine 🇺🇦🇺🇦🇺🇦🇺🇦🇺🇦🇺🇦🇺🇦🇺🇦

I hope you're doing well with your New Year's resolutions. If you missed last week's newsletter, I offered my four tips for keeping them up - you can find them online here.

As I'm not yet back into my usual rhythm of working and writing, I'm going to digress again this week from my regular format.

You may have been reading about the rise of "AI content generators". These are tools that use artificial intelligence to generate "human-like" content in response to descriptive requests. Elon Musk is a founder of a company called OpenAI which produces one of the leading AI systems (called GTP-3).

I regularly use various AI content generators, and you might be interested to see the quality of content they can generate. So, I've chosen three topics relevant to the newsletter and instructed an AI-writer to produce a summary of each:

⭑ Why using gym machines is less beneficial for people over 50 than functional or body-weight exercises ✔
⭑ The relationship between prebiotics and brain health ✔
⭑ Any evidence supporting an association between the Pfizer Covid vaccine and arterial fibrillation in people over 50 with existing high blood pressure ✔

I have not edited any of the responses from the AI-writers, but in one instance, I have refined my initial question to get a more specific response.

Here goes, let me know what you think.

Caveat: I have not fact-checked the detail of the content generated by the AI-writer so exercise discretion in how you use this information.

01 Are Gym Machines or Bodyweight Exercises Better for Over-50s?

Gym machines can be useful for seniors and people over 50 years old, but they are not necessarily the best way to maintain longevity and balance. Machines are designed to isolate a certain muscle group and usually require you to sit or lay down in order to perform the exercise. This means that you are not engaging in any dynamic movements that require balance, coordination, and body control.

Bodyweight exercises and functional exercises are more beneficial for this age group as they involve balancing and stabilizing the body while performing the exercise. This can help improve posture, strengthen the core and back muscles, and provide much needed balance.

Overall, while machines may be beneficial, research suggests that bodyweight exercises and functional exercises are more beneficial for seniors and people over 50 years old when it comes to maintaining longevity and balance.

02 The Association Between Prebiotics and Brain Health

Prebiotics are dietary fibres that are not digested by the body, but instead nourish beneficial bacteria in the gut. A growing body of research finds that prebiotics may have a positive impact on brain health.

A recent study published in the journal Neuroscience in 2019 found that prebiotics reduce anxiety-like behaviours and improve cognition in mice. The study demonstrated that prebiotics increased the production of GABA, an important neurotransmitter involved in regulating mood and behaviour.

In addition, a study published in the journal Brain, Behavior, and Immunity in 2017 found that prebiotics increased levels of the hormone oxytocin, which is linked to social behaviour and stress levels. These findings suggest that prebiotics may have a positive impact on mood and behaviour.

Further, a study published in the journal Neuropsychiatric Disease and Treatment in 2018 found that prebiotics improved memory performance in adults with mild cognitive impairment. The authors of the study concluded that prebiotics may be an effective dietary supplement for people with cognitive impairment.

Overall, the research suggests that prebiotics are associated with improved brain health. Prebiotics may help reduce anxiety and improve cognitive performance. Therefore, it may be beneficial to incorporate prebiotics into your diet.

03 Association Between the Pfizer Vaccine and Arterial Fibrillation (in people over 50 with existing hypertension)

The Pfizer Covid vaccine has been shown to cause arterial fibrillation (AFib) in people with existing high blood pressure or other existing cardiovascular impairments. A case series of four patients who developed AFib within 24 hours of receiving the Pfizer Covid vaccine was reported in the journal Clinical Cardiology. These patients had preexisting hypertension, previous history of AFib, or other underlying cardiovascular disorders.

Another case report described a 63-year-old male who developed AFib within 11 days of receiving the Pfizer Covid vaccine. This patient had a history of hypertension, diabetes, and other cardiovascular risk factors.

A third case report described a 45-year-old female who experienced AFib within 14 days of receiving the Pfizer Covid vaccine. This patient had a history of hypertension, diabetes, hyperlipidemia, and chronic kidney disease.

These case reports suggest a possible association between the Pfizer Covid vaccine and AFib in people with existing high blood pressure or other existing cardiovascular impairments. It is important to discuss any preexisting conditions with your healthcare provider before receiving the Pfizer Covid vaccine.
