Fully-autonomous driving can mitigate this; you will still be commuting, but with an added benefit of being hands-free (to check your e-mails, to finish up your TPS reports, to nap) for much of society this can be highly efficient if utilized correctly.
I got just a little further than you, until I reached "women make the best mathematicians" where I instantly ALT-F4'd Google Chrome and added 'medium.com' to a permanent blacklist. Truth of the matter is, math IS a high-IQ game, albeit average intelligence specimen can become semi-competent with time and practice (the payoffs of this pursuit are negligible)
I glimpsed at the content for 30 seconds. This does not look anything like a computer science education: "Pencil Code", "Blockly", "Coding Adventures", "Craft Small Projects in HTML/CSS". These are just glorified baby-games for 5 year old's; or at the very most a stupefied introduction of basic development for girls and malnourished Indian children.
Early-mid 2000's kid here. I roamed without second thoughts: Explored forests, cities, trespassed on forsaken enchanted lands and everything in between. I admit there has been stark differences in outdoor activities; but this isn't a "it's too dangerous for Johnny to go outside" scenario, it's a "Johnny is too glued to his iPad 8.0 to enjoy going outside" scenario.
I do not know what is so difficult about not eating sugar. If "without sugar" means no added artificial sweetener or added sugar (as according to this article) then I have not consumed sugar for many many years; the same goes for our ancestors, farmers, etc. I do not know if this is a case of crack-like addiction, or a case of "what is the point? you only live once, you should indulge in pleasures" either way it need not be difficult if you simply, as an example, substitute your candy for fruits (fruit cultivation is a far-cry from what it used to be, but I do not want to get into an argument about this)
Despite all of this, take it from me: The benefits are overrated
Ironically and amusingly enough, I was my happiest (and seemingly healthier) when I was a little boy running around all day outside eating candy or chocolate to my hearts content.

That's a dangerous thought that everyone has. You were indeed happier and healthier, because you had a new body that could heal more faster, and your metabolism was through the roof.
After 25, wear and tear starts to become noticeable, metabolism slows down, physical damage heals slower, pain lingers for way longer, you get less endorphins.
But these days everything is over-sweetened, fucking bread is sweet as hell for some reason. So cutting down on sugar is more than just not putting it in your tea/coffee and not eating cookies.
Every life extension discussion derails into debates about foreverness; and therein lies the problem: humans of all backgrounds (even today) are dropping dead of health problems at 60 years of age. Thus, foreverness is science-fiction with our current understanding. Baby-steps first perhaps? Regardless, many agree foreverness is not possible - and if it was - I would not want it.
It's a red herring anyway. The valid question is, would you prefer to remain alive today? You're free to answer in the negative at any time, but it would be nice not to have the decision taken from you by mere biochemistry.
The valid question is actually would you prefer to be healthier today. Aging affects everyone's health (perhaps after a certain age) whether they currently realize they have some acute condition (such as cancer or imminent death) or not.
To sum up everything in this thread: Life becomes less appealing as you get older. You lose friends because "career" and "kids" and "my wife would not agree to this". The novelty and wonderment of being a child is LONG GONE, ie. your brain oxytocin, serotonin and β-endorphin receptors are all but ERADICATED from the grudges of the mundanity of your boring 9 to 5 suburban lifestyle. No time for friends and riding bikes and adventures in the forest and first-kisses under the tree and kickball, those TPS reports need to be finished as soon as possible. You are a walking zombie; living in a biological sense, but not really living. Do not fret because your life is nearing it's end surely but slowly; cell stress, telometre shortening and calcium disposition within collagen has you taking an aged "old-person" appearance as you are scientifically dying from the inside-out as the seconds on the clock tick and tock and by the way is Docker or Vagrant better for deploying a NodeJS + MongoDB app?
Completely on the contrary. As someone with a wife and kids, suburban home, a tech job and similar decisions to make (react or anguar2).
Never in my life I had so many opportunities to do fun things but I simply changed my preferences. I still like riding bikes and hiking and hanging out with friends (both couples with kids and just guys night out) however, I much more enjoy alone and quiet time than before. Reading, taking a Coursera course, hooking into my htc vive, finally learning the guitar solo from the wall part 2, learning to read music notes and play the piano.
I feel much happier now than in my childhood. I have more friends than I have time for. And much less urge for company. I feel perfectly fine with just my family singing me "Happy birthday".
Sounds like you would benefit from an Ayahuasca retreat or weekend on LSD. It gives you a new perspective on your life and also helps most people who are open to the possibility realise there is a lot more to discover.
If you are under 1000 years old, I'm sure you've only scratched the surface.
You are completely right.
The problem of poor, dirty, violent, urban-youth infested communities is not fully solved.
