Probably would not be very useful. You would lose motor control of half of your body. When the left half of the brain sleeps, you would be a total mute as well.
The brain is fully developed by age 25 and starts to lose mass from then until death (see: http://www.ncbi.nlm.nih.gov/pubmed/19283594). Brains of 90 year olds can be just 60% the size of a young adult. Neurons do not repair well and they (or rather, stem cells) aren't programmed to divide after the skull runs out of room.
I would not worry, though. The brain is very flexible. If you keep your mathematics sharp, you will lose less useful things like old memories instead of skills. Many professionals work in difficult jobs (say surgery) well into their 70s by keeping their skills in use.
The problem is that non-retina images get doubled in size on a retina display, so it looks blurry. I suggest providing 2x sized images. You can use media queries to show different sized images or rely on down-sampling. There's a few different strategies.
Looks like all the font strings are images (makes sense, most of those aren't web fonts). I would also love retina images, since fonts can look vastly different between say, a MacBook Pro, a windows desktop at 1080p, or a low resolution remote desktop.
This experiment is quite flawed, at best. At the minimum:
- Oversimplified models of biochemistry (way, way more complex than insulin = fat)
- Sample size of 2 trials (leaving one result)
- No measure of insulin (not a one-to-one relation to blood glucose, also released in complex cycles)
- No control of meal time (blood glucose varies)
- No control of meal contents (assuming both meals are equal in content)
- No control of fasting time (blood glucose varies)
I have had to treat diabetes in cats so I got quite proficient with measuring blood glucose levels. Even when you control every single factor as much as possible (animal eats the same amount, at the same time, every day), blood glucose varies wildly. Non-diabetics have the same massive variance, as I have done blood glucose curves to myself and to others.
This experiment is unfortunately pretty much useless. The body is a very complex organic machine with lots of parts that evolved independently of each other. There aren't neat little one-to-one relationships that can be tested easily. It is full of genes that modify genes that modify genes that secrete hormones that modify pathways and brain patterns and so on.
I'm going to agree with this choice, especially since the OP wants something new.
Since the OP comes from a JavaScript background, the static typing and low-level of Rust will be great things to learn. One also gets first-class functions that aren't insanely verbose (a problem with C# and Java 8). The structure of the game engine will also translate well to the more popular languages in game dev (C++, C#, Java).
OP, keep in mind that older languages do keep getting updated so that they stay fairly modern. In particular, Java 8, C# 6.0, and C++14. C++ especially is very common in the game dev world.
"Fixing" government web has nothing to do with young people. I contracted for 5 years for the Department of Defense doing full stack web. Yes, most people I worked with were double my age or more, but many of them are very talented and eager to implement new technology.
The problem is the massive, unbelievable amount of red tape to get things done. Software stacks and browsers have to get approval and re-approvals, a years-long process. Code has to be written in something stable, not something trendy. The programmers spend more time writing documents and attending meetings than coding. There are meetings about meetings and the layers of management are infinitely recursive (managers for the managers).
Start-up culture and tech trends just don't work at the scale of government, for much the same reasons massive corporations move glacially. Just add even more layers of management, congress, civil service employees that cannot be fired, and tax dollars to the mix.
I enjoyed my time working in government web, but "youth" isn't really an answer.
