In your first link the narrator says he "doesn’t understand the physics of it" but there's really no physics involved (ignoring scatter). It’s just a consequence of the math. It’s relatively easy to understand if you think of it in terms of the surface of a sphere. There is a fixed amount of light coming from a point source, and as the light travels outward you can think of it as being spread over the surface of a sphere. Since the surface area of a sphere is 4pir^2, if you double the radius the area quadruples, and therefore the light intensity at any point on the sphere drops by a factor of four.

edit: And now after rtfm I see there's a nice demo of this!


I have the same and really like them other than the BTE still require an induction loop necklace for Bluetooh.


> I understand the self-interested desire for the ultra wealthy to have lower taxes on an individual level,

I don't. It seems like mental illness to me


What is so hard about understanding their desire? They want to keep more money for themselves so they can buy more yachts, invest in more things, whatever. This is just how humans are.

It's up to policy makers (i.e. government when it comes to taxation) to structure the system to mitigate the inherent self-interest that people have. Obviously that's easier said than done when the ultra-rich buy off the politicians, but human nature just is what it is.


The thing is they have so much money they can't buy enough. Even if all they do is consume, consume, consume they will still be trending upwards. In effect, every yacht has a negative price tag.


It bears the same hallmarks as any other addict: the next hit has to be even bigger than the last, and everyday enjoyments in life are practically invisible to them. Their drug of choice may be different, but the outcome on their life, relationships and society is largely the same.


> This is just how *some* humans are.


To clarify, I don't mean all humans want to keep all money for themselves even when filthy rich, I just mean that all humans are self-interested. The extent to which that governs our behavior of course differs and I agree there are people who willingly sacrifice to help others.

To clarify a bit...

I meant I understand it in the sense that to get that wealthy in the first place you have to have a special kind of self-interested sociopathy, so in that regard I understand their desire. Not that I agree with it.


Every human is self-interested. Fortunately there are a lot of good people out there who try to temper that instinct, but remembering that everybody by default has a "what's in it for me" line of thinking (even if consciously attempting to subjugate it) is important for understanding as much as we can about how the world works. I don't think a sleasy real estate agent is behaving any differently (by jacking up fees, putting people in properties that may not be in their best interest, strong-arming FSBOs into listing with them) than the billionaire is, it's just the scale of their blast radius that is different. That's not to equate the two, because obviously scale matters, but the underlying motiviation is largely the same.


Gotcha. I should have realized you meant that from the rest of your post.


Kinesis Freestyle Pro? I've got the non mechanical version (mechanical wasn't available when I purchased) and it's held up for many years. It's a great keyboard IMO.


The Freestyle Pro is almost a good keyboard. The Esc and function keys are all offset to the left by one key compared to a standard layout, which drove me nuts. I have a Freestyle Edge RGB now, which I like much better. (Though I replaced the wrist rests with some from Goldtouch.)


I really like my Kinesis Freestyle Edge with the tenting kit. I’ve been using it for around 2 years and no complaints.


Thank you, I'll take a look.


Not to mention that the rear brake comes into play as applying the rear brake will transfer weight to the front allowing you to apply your front brakes harder.


Not in my experience (20yrs). If it's all-in-or-we're dead, you either do a stoppie and hope, or do a deliberate lowside and also hope someone will patch you up once they dislodge your parts from wherever you end up in.

In either case it's front brake. A bit of tilt for the second case. The rear brake is not needed at all.

If it's just a overspeed corner, you try to slow down gently, while maintaining both wheels on the trajectory. So just a little play with throttle and just a little front brake so that the bike stays balanced so to say. No rear brake at all because dropping the throttle a bit is all that's needed for the rear wheel.

If that is not enough, you're not going to make that corner, you have had too much speed coming in, and you will pay for that right now by crashing into something.

I learned this in 1990s when I first started riding.

Those are the basics.


With all due respect it sounds like you could use a refresher on motorcycle physics.


2% is quite low. Most of the FIRE community would consider even 3% quite conservative.


3 million invested means you can withdraw $100000 annual income with virtually no risk of ever going broke. That is financial independence. $10MM is way too high a bar.


Talk to your Dr obviously, but you may just be running too fast. There's lots of Couch to 5k programs that start off with 30s run intervals with walking in between.

With running you need to play the long game and slowly build up your pace, total mileage, and number of weekly training days. It's hard to be patient, but it seems to be the secret to minimizing training injuries.


I'm not a run streaker, but am an avid runner and if you "only" need to run a mile you really only need to find 15min in a day to keep your streak alive.


A lot of runners (me included) are data nerds and record every runs date/time, distance, pace, weather, shoes worn, how we're feeling, temperature, elevation gain etc.


Watch the start of most race events and the first thing that people will do as they start is turn on their watches.
