There's a subset of people in Ireland who are legally required to write down an ID on their vehicle, that can be matched to a name/photograph in seconds.
Unrealized gains can be taxed - for example, Ireland has a Deemed Disposal tax on ETF investments, where after 8 years, any gains are considered to have been realized and tax is due (even if no sale has taken place)
Definitely not new - as someone who was diagnosed with Haemochromatosis in 2017 - I was first prescribed phlebotomies until my general iron levels reached a level that my consultant was happy with.
Once I hit that level, I'm able to donate blood about twice a year (once every six months) to maintain (that, and a slightly changed diet to avoid high iron food)
You're focusing a bit much on the Developers bit.
It's not just Developers who are working through the code-base.
As a lame example - Incident Response/SRE will also be trying to get their heads around changes being made - especially if they're responding to an outage, and trying to figure out what change broke production - and why it was made.
Not everyone will know every bit of the project as intimately as the Dev team - and having a good commit message will help any unfamiliar response team mitigate, or escalate accordingly.
{Tests, Code Comments, Documentation} are 3 distinct places to trawl through when quickly going through git blame.
The commit message is one place - and gives the author an opportunity to speak directly with a future developer over the place-in-time-context that this change was made.
The first line (or atleast, the first 80 characters) should be a quick summary - so you can quickly browse via git blame.
But the actual commit message should consist of History/Motivation/Context - so that someone who's going through the blame can understand why a certain change was made, and what the context was.
Behaviour by the rest of society is influenced largely by public policy.
In Ireland, investing in Housing/Land is largely one of the best investment assets you can own due to the lack of Capital Gains or Deemed Disposal rules.
Helmets prevent a particular type of injury - traumatic brain injury
This is true for all types of transportation including driving.
Traumatic brain injury is a common outcome of an automobile collisions - yet we don't see people with the same concern for introducing mandatory helmets in day-to-day driving.
A few of the offices even have a pool (Google Dublin, and soon Google London)
Because the buildings are usually located in very central city locations
- I've often used the offices as a way to kill time til' check-in opens for hotels after a long-haul flight (grab food, caffeinate, have a shower, etc)
Recently I took a night train between Stockholm and Copenhagen.
Showered in the Stockholm office, walked 5 minutes to the train station, slept, woke up in Copenhagen, grabbed a hearty breakfast in the CPH office.
It's a little perk that is honestly vastly underestimated

Additionally, in plenty of European Countries, it's pretty common to write your name on your address: https://c8.alamy.com/comp/B01RP4/personal-name-plates-at-blo...
