Eat more fibre Most of us eat only half the recommended 30g a day. But start slowly – our guts don’t like rapid change

Eat the rainbow Choose colourful fruits and vegetables and try to eat
30 different plants, nuts and seeds every week

Eat foods rich in polyphenols These include dark chocolate and red wine

Eat fermented foods Tim Spector favours kombucha, kefir and kimchi, as well as unpasteurised cheeses

Eat more omega 3 New research suggests a relationship between gut microbes, omega 3 and brain health

Let kids play with dirt and dogs Jack Gilbert’s research has shown that since the gut’s population is seeded in early life, allowing small children to dig in soil and play with domestic animals can undo a lot of the damage modern lifestyles do to our microbiomes

Instead, parents can talk about exercise as being important for general health and wellbeing, rather than a way to lose weight. Families can also normalise eating healthy meals, rather than overtly talking about specific foods being bad for you. We all like a treat, after all, so it seems counter-productive to teach children to feel guilty about having one. In fact, enjoying treats is known to be key to a healthy attitude towards weight. Watching TV cooking programmes featuring healthy food, can also subtly encourage children to eat healthier foods. - https://www.bbc.com[..]e-best-way-to-teach-kids-body-confidence

How to train your brain to become more curious - https://www.fastcompany.com[..]how-train-your-brain-become-more-curious

Recognize that you’re a creator, too—when you do, you’re more awake and alive and contributing value to the world.
Relish your thoughts because your thoughts are ideas, and ideas can become real.
Stop for a few moments a day; pay attention to your thoughts and accept that your thoughts are creation.
Reverse engineer and create something out of what you might have just consumed online (consume to create).
Start noticing things. Creation manifests in many forms. Creation and art are not what you were told growing up.
Write down or record a question, thought or idea, immediately and right now.
Record a stream of consciousness, even if it is nonsensical, from your brain to paper or a voice recording. Do not edit or fix typos or grammar. Do not feel compelled to share it with anyone. Try to do this once per day. This can be intentional or unintentional. Snatch an idea from thin air, don’t let it escape.
Reject shame, embarrassment, or even celebration at your idea. Be compassionate and let it live for a while.
Create without judgment or consume with intention to build on or improve on an existing idea. This is still creation! This is not a diary or journal. This is a chance for you to become aware that you are a creator and have been creating every day since you were born.
Finally, organize your desk, line up pencils, categorize your books or tools, clean one cabinet and reorganize it. Look at the results with a creative eye, not a critical one. The visual myth that the real artist has a messy, paint-splattered studio is false. Organized things can reflect creativity as well. There can be art in order, even if it’s the way you line up bottles in your refrigerator. If you need a reminder, just watch how Marie Kondo folds a T-shirt.

aging

She found that people who had positive ideas about their own ageing (who agreed with comments such as "I have as much pep as last year" and who disagreed that as you get older you get less useful) lived for an average of 22.6 years after they first participated in the study, while the people who felt less positively about ageing lived for just 15 years more on average.

In this study, it didn't matter as much what people thought about the physical implications of ageing, what mattered was whether they believed they would still develop and grow mentally.

Your Hands as You Age - https://www.webmd.com/healthy-aging/ss/slideshow-your-hands

In an eight-week clinical trial conducted with adults between 50 and 72 years, researchers determined that biological age could be reversed over three years by using a treatment that included diet (low glycemic fruits, eggs, and liver), at least seven hours of sleep a night, exercise (30 minutes a day for five days a week), meditation and breathing exercises, and supplemental probiotics and nutrients. Cumin, turmeric, green tea, and mushrooms were also included in the recommended diet. The trial was conducted by Kara Fitzgerald, author of Younger You: Reduce Your Bio Age and Live Longer, Better, and her team. - https://www.zmescience.com/science/science-aging-epigenetics/

Some nice tips of having presentation

Do not spend half of your talk "motivating" your topic.
Have a rhythm. Let's be honest
Tell a story.
Make sure you solve an actual problem.
Not everything you say has to be brand new.
Never let anyone touch your slides after you have last seen them.
