With plus lens therapy, you only wear the plus lens while doing close work. If you were wearing the plus lenses while looking more than a few feet away, you wouldn't be doing plus lens therapy.
DHH said there are things about the "large tent" aspect of rails that are annoying. That's not the same thing as being unhappy with the overall direction of the project.
The second doesn't follow from the first. At most, you could say that people MAY calculate that running a tor relay is no longer worth it, but you could also say that without bringing up the (almost completely unrelated) daycare example.
Tried Etymotic earbuds? They come with a bunch of adapters to fit different sized ears. My model is of course discontinued but the mc5 looks closest. http://www.etymotic.com/ephp/mc5.html
edit: unlike any other earbuds I have tried, they are engineered to survive the inevitable wax-plugging. Just replace the filter & you're back in business.
1) you have a serious, unaddressed medical condition (please seek help!)
2) you're trying something far beyond your normal activity level. There's no rush, work up gradually and your body will adapt. If a walk around the block is a challenge, start there. Repeatable training sessions over time is what makes change, not beating yourself up in the name of 'health'.
2-3 hours a day x 5 days a week -- 10-15 hrs -- is a huge amount of time to spend on weights.
A Starting Strength routine shouldn't take more than 3-4 hours a week, and you'd be moving way more than your bodyweight.
Or, if you can find room in your dwelling for a barbell and plates, Pavel's Power to the People program would take a total of 2-3 hours a week. Again, you'd be developing strength, rather than endurance.
Having said that, if you've found something you're happy with, cool. The routine you actually do beats a theoretically superior routine you don't get around to.
I'm at 3.5+ years on my current white macbook, and finally about ready to get a new one. Use it most of the day, most days for web and misc development.
Thinking a macbook pro with SSD & 8GB has a chance of lasting even longer.
Haven't read the new book, but Taubes' previous work 'Good Calories, Bad Calories' makes a strong case that there's shockingly little experimental evidence in favor of the conventional wisdom that "eating better" means a low fat, low calorie diet.
