Basic (office) exercise and stretches. I've gotten old(er) and really wish I'd done those for my neck and shoulders.

It makes such a difference, this and posture. I've had so many injuries and joint problems from not doing this, luckily I've made it a routine in my 30s

>A person can also learn a few guitar chords and possibly play a carefully-chosen song in that time. He can't. He'll know how to play it, but it will require many hours of repetitions to reach enough speed.

maybe spend an hour ... every day!

Fasting... in fact, if you simply stick to just one simple rule which is, eat ONLY when you become hungry, you will reap rewards. Hint: Not everyone needs 3 meals a day.

In order to this, you need to become aware of your body and mind. And for this, you need to learn Meditation which is simply a practice of mindfulness for a set period of time.

> CPR/Choking/First Aid course is probably close to an hour. What can you teach in only an hour? I work with some people who teach basic first aid, and the shortest course any of them does is 4.5 hours.

A broad first aid course will take more than an hour. (The Wilderness First aid courses I've taken are a full weekend.) However, you can cover a lot of the basic things you're likely to encounter in civilization pretty quickly (if very cursorily). Probably most important is the basic approach to take, things to watch for, blood safety, etc. It's not going to be a real first aid course but a quick familiarization of t…

A basic Life Support Course is like 2 hours (maybe 3). Actually did it in the morning then spend the afternoon testing everyone.

A Essenial First Aid at Work course is 8 hours (this is the legal requirement for FAW in the UK)

A Full First Aid at Work is 32 hours.

A EMT-B in the USA (min needed to do, to get on an Amblance) is 50 hours

The basic training for amblance in the UK is about month with a week training in driviong with blue lights

Want to be a Paramedic well that is a 3 year degree

Want to be a Nurse that again is a 3 year degree (and no you can't do one and swap for the other)

Want to be a doctor well that 5 years plus a few more years training on the job.

Ok if you want to get a medical Gas Qual well you looking at about 8 hours or so. Patient and casualty handing are both about 2-3 hours each.

It is not how it works at all. The fallacy here is that a human body is a machine with well-defined intake and output. How would one even know what is "exactly" the right amount? Over a year we consume 1 million calories. If one were just 0.1% off of systematically eating more (or less) than required then according to your model one would end up being 200 pounds fatter or 200 pounds leaner ... do you think that anyon…

Another question to pile onto this. Maybe you're the right one to ask. I was always taught that the body uses up its glycogen stores before burning fat. But if that were true even a small calorie deficit would gradually use up our glycogen stores and we'd be walking around without any after that. Plus before losing any fat you'd have to experience a glycogen crash/wall which most small deficit dieters don't experienc…

Very roughly...

Generally what fuel your body burns depends on the intensity of work you are doing, so if you're walking you may be burning 80%+ fat, but if you're running a 10k you may be 80% glycogen.

However, if you eat too many carbs at a meal (beyond what you need in the next few hours), your body needs to get that excess out of your bloodstream, so it will do a combination of: - fill your muscle/liver glycogen stores (limited size) - burn any excess carbs in preferences to stored fat - convert any excess carbs to stored fat

Once it's got rid of the excess carbs from your bloodstream, it will return to burning whatever the normal ratio of fat:carbs is for you.

Consequently, if you always eat too much carbs, you'll gradually pile on the fat, unless you're doing large amounts of training which depletes your muscle/liver glycogen, e.g: elite athletes.

Read Schopenhauer „The Art of Being Right: 38 Ways to Win an Argument”. It’s a short read, but mind opening if you’re new to the subject. If it seems too long then just read some shortened version. If you still have some time after that then go to “list of cognitive biases” Wikipedia entry and continue there. I believe it is crucial to understand what tricks others are using in arguments. And also what’s our cognitiv…

Looking at Amazon reviews of it, one of the commenters says it's a rehashing of the 1896 book "Art of Controversy", available online free (public domain). A quick search online shows an example of it here: https://ebooks.adelaide.edu.au/s/schopenhauer/arthur/controv... Does it seem the same to you?

All are in public domain now. Read the one i mentioned as it is shorter read. If you like it then go of the other one.

Setup and learn how to use Anki to practice spaced repetition. Going forward you can now decide what you would like to remember (so long as you are willing to spend 5-15 mins a day reviewing)! People's names, that command you always look up, your credit card number, interesting statistics (e.g number of passenger miles per death for bicycles vs cars vs planes) foundational facts in your field that will allow you to p…

There's also Quizlet which is similar but I find it better because you can preview entire pre-built card decks on it which makes it searchable on google https://quizlet.com

You can pretty easily search for quizlet decks and then import them into Anki so long as you don't need two-way automatic sharing. Google for extensions, depends on Anki version

I regularly make my own dressing as well! I have a few basic recipes—most are pretty much the same as yours. One I like in the summer especially is a really simple one: + 2 parts olive oil + 1 part honey (try and make it good wildflower or clover honey) + 1 part squeezed lemon juice (add some zest as well if you're feeling energetic—I hate cleaning graters) + Salt & pepper to taste

I do something similar. Mine is olive oil, balsamic vinegar, and a tsp of really strong mustard. I put mine in a small Tupperware in the fridge, that way I can shake it up easily to mix, and I just add to it as I get low.

I use the exact same technique if I’m trying to keep a batch going.

How to cook for yourself, really, really good food. I no longer crave restaurant food, and all of the really important things I learned about cooking take just the time to read it, hear about it and then try it. All without any special hardware. A few examples: 1. Cooking jasmine rice: rinse it first, 1 c. water to 1 c. rice ratio. Bring to boil, turn down heat to lowest setting. Leave lid /the entire time/. Fluff th…

Very useful. When I was living solo in Ahmedabad, I used to cook a lot of Khicdi (It is combination of Rice + pulses cooked) which is nutritious, light and very cheap to cook. I must have saved 80% of the money had I been ordering the food from outside.
