Re: Most people could live past 130 if they choose to, while aging very little
he never took turns?
or he never came back the same road on the other side
I get your point, but this..
damn, how do you always drive with the same side facing the sun

I don't think it sounds unreasonable. Think of a truck and how the driver will be sitting on one side. Even when the Sun is on the other side of the truck, the side of his face that is away from the window will be shielded by the roof and windshield of the truck (since glass is mostly opaque to UV radiation).
Now that is quite something. I do my best to avoid the sun as much as possible. It's been a lifelong aversion. Anyone who seeks it out kinda deserves what they get. It's pretty clear what'll happen to them.
Sunscreens actually do a pretty good job of "deflecting" the sun's rays. Those that use titanium dioxide aren't soaked into the skin(It covers it), destroying any argument skeptics have of "dangerous chemicals being absorbed".
I'd say using a good sunscreen(fps 30+) is all you need to enjoy time in the sun without worrying about having major damage done to your skin.
P.S. A common analogy used is comparing the human skin to a grape. Now human skin is vastly more protected than that of a grape, but leave a grape out in the sun for a while and it turns into a dried, wrinkly raisin. Over time, due to excessive exposure to the sun, human skin will eventually begin to dry up and form wrinkles just like that grape did as it turned into a raisin.
Yes. Most of the signs of visible aging is due to photoaging caused by exposure to the Sun.
Here's the same picture posted above but in mirrored form:
The mechanisms are a bit different though but the end result is pretty much the same. UV exposure causes deterioration of collagen and elastin fibers which is what gives youthful skin its smoothness and firmness. The changes that a raisin experiences has got much more to do with the loss of moisture and less to do with UV damage although loss of moisture is something that also affects aged human skin too.
Regarding grapes, grape seed extract is one of the best common antioxidants. You can get it rather inexpensively, in bulk, from http://www.herbstoreusa.com/gs-100g.html. But be careful that you don't take too much at once - 1 or 2 tenths of a teaspoon at a time, mixed in your nutrient smoothie. The stuff is bitter as all get-out. Did you ever chew a grape seed?
The skins of grapes also contain resveratrol which might have age inhibiting properties (although the research isn't entirely conclusive).
Calorie restriction is probably the most promising method of increasing longevity but whether or not it actually works on humans is unknown. It doesn't work for some species apparently and it works much better in rats than in mice for example:

It might be worth looking at examples of people who don't seem to have aged a lot too. Jared Leto, for example, is a vegan who is chronologically 45 but looks closer to 28-32:
