+Slowing Aging
+=============
+
+- Avoid DNA damage (wear sunscreen)
+- Eat less - caloric restriction
+- Eat less protein
+- Do exercise (HIIT)
+- Be cold
+- Be hot
+
+... these trigger longevity genes to trick body into preserving genome
+
+
+Reversing aging
+===============
+
+Theory
+------
+
+- Shinya Yamanaka discovered 4 factors that reset epigenome of cell back to pluriportent stem cell
+  - Myc, Oct3/4, Sox2 and Klf4
+  - dont do it all, would turn into tumor
+  - suggests there are ways to revert cells and reverse ageing
+- David Sinclar's lab reversed aging in old mice so they could see like they were young again
+  - used 3/4 of the reprogramming factors, not Myc as causes cancer
+  - can turn system on and off to limit reversal
+
+
+Resources
+=========

+- Veratasium How to Slow Aging:
+https://www.youtube.com/watch?v=QRt7LjqJ45k
+
+- JRE David Sinclair #1:
+https://www.youtube.com/watch?v=HOTS0HS7aq4
+
+Notes:
+Calorie restriction, mostly vegetarian diet, avoid sugar and carbs. 
+On weekends, he exercises at the gym and then sits in a hot sauna before plunging himself into an ice-cold pool, as well as tracks his biomarkers regularly.
+Takes vitamin D, vitamin K2, and aspirin. 
+Takes each morning: resveratrol, NMN, and metformin
+
+- JRE David Sinclair #2:
+https://www.youtube.com/watch?v=ZGLL77wYxe8
+

+7:00 NMN and NAD+, metformin and exercise
+18:00 Sinclair’s family went on a safari
+48:30 back to the anti-aging book, longevity
+52:20 Sinclair’s healthy 80 year old father: “He’s fitter than me”, his rebel grandmother
+1:10:00 intermittent fasting
+1:15:50 I.V. NAD+
+1:18:00 nutrition, yogurt and other food
+1:32:00 resveratrol, colorful foods
+1:41:00 sleep
+1:45:40 what should people be doing? (Sinclair is wrong about airport scanners)
+1:48:25 NMN and NR online
+1:50:25 CRISPR/ genetic engineering

+Notes from Andy
+---------------
+
+Mastering your mind:
+- can you control yourself?
+- can you sit still physically?
+- can you control your mind?
+  - can you concentrate on a simple object and nothing else?
+  - can you have no thoughts?
+    - can you free your mind from remembering the past or future?
+    - can you have no visual images / sounds?
+    - can you stop your inner monologue?
+
+
+How to meditate:
+- these steps are very gradual, not distinct steps:
+- master focusing in the present (1-2 years)
+  - disregard the past and future
+  - focus on noises in the present. can jump around or listen to all.
+  - on failure gently pull back to the present
+  - mastery when you can do this for an hour
+  - can start with shorter sessions
+- master focusing only a single element in the present
+  - for example, your breath
+- master stopping the monologue
+  - stop talking to yourself
+  - stop making comments
+  - stop the chatter
+- master total absorption into that single element
+  - deeper focus into the element
+- Samadhi state
+  - can only experience your own, dont read the wiki
+  - Andy reached this only once, he felt omnipotent
+
+- this becomes an intrinsic skill like talking and walking rather than a motor skill like throwing?
+- if you dont use it you lose it?
+- one you reach Samadhi your mind always meditates

+
+Solutions
+=========
+
+Desires
+-------
+
+- Open source
+- End to end encryption
+- Portable data store - md (or exportable)
+- Images
+- Rich text editor WYSIWYG
+- Linking notes together
+  - to whole note or header in note
+- Sync
+- Mobile support
+- Folders
+- Undo / versioning
+
+
+Reviews
+-------
+
+Joplin:
+- UI is very fast
+- has its own sync server now, wait to mature?
+- scroll in render view glitchy / laggy when zoomed
+- WYSIWYG editor breaks some markdown
+- clicking links in WYSIWYG requires ctrl
+- can't see note names in notebook tree, so will be hard to find
+  - maybe that's better?
+- mobile app lacks WYSIWYG
+- mobile app md editor scroll shitty
+- slow to edit notes in mobile app
+- white flashes on dark mode desktop theme when switching notebooks
+- Todo feature is cool. can make each note a todo and use the body to add context / info
+  - easy to rearrange todos
+
+Obsidian:
+- highly reviewed, looks sexy but needs more contrast
+- no WYSIWYG editor yet - planned
+- has graph and backlinks
+- not open source
+- files stored as plain text
+
+
+Wiki.js:
+- Supports LaTeX
+- Support Markdown (it also supports formats such as html)
+- Works in-browser (and therefore can be accessed on any device)
+- Editing is easy (although this sounds like a "duh" feature, many self-hosted note apps are more like static site generators)
+- Uploading files is simple
+- Has multiple backup options (I use GitHub and .gitignore the textbooks)
+
+
+Boostnote:
+- no mobile support
+
+Trilium:
+- great encryption
+- poor mobile support, Dom uses telegram as a buffer
+- fully tried it, mobile is just too broken
+  - doesnt scroll all the way to the bottom of folders and note contents
+- lots of other minor bugs
+  - parts of UI not updating like archived notes
+  - randomly refreshes the page
+  - header sizes all look the same
+  - today note button is slow to load
+
+Simplenote:
+- not self-hosted
+- no folders
+
+Turtl:
+- buggy app
+- bad organization system
+
+Org-mode
+- needs emacs
+
+Taskwarrior:
+- command line only
+
+Zim:
+- no built in sync
+- no mobile
+
+TiddlyWiki
+- no built in sync
+- one html file
+- modern browsers block some file features?

+- goes over the three types of note-takers
+- librarian: likes to catalogue, usually write-only -> evernote
+- gardener: likes connecting ideas in their own way -> roam
+- architect: likes designing processes and structure -> notion

+
+Formatting / Template
+=====================
+
+Unformatted info can just be sentences, paragraphs, or points.
+
+
+Section
+=======
+
+Place two empty lines before the section header, empty line after
+
+
+Subsection
+-----------
+
+Sub-subsection:
+No linebreak for text within a section
+
+Generic lists or steps:
+- dash then a space
+- lower case for prose
+- Data points: gets capital
+- like this
+  - sublists
+  - two spaces, dash, space
+
+Todo lists:
+o unfinished task
+v finished task (looks like check mark)
+x cancelled task
+
+- I wonder if I should just use markdown?

+Timezones
+=========
+
+NEVER USE .replace(tzinfo= EXCEPT FOR WITH UTC!
+
+Assigning timezone to parsed string:
+- example, you get a text timestamp and parse it with strptime
+- solution:
+t = datetime.strptime(timestamp, '%Y-%m-%d %H:%M:%S')
+tz = pytz.timezone('America/Edmonton')
+result = tz.localize(t)
