If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

I dont drive a super sized hummer, I drive a civic. Operating expenses for a civic are $0.12 (my real expenses as calculated over the past 4 years of ownership I average 44mpg on the highway at 75mph)

$273.60 there and back for 3 people plus all the luggage I can fit in the trunk. That is the real cost and is dead close as I have made this same run 4 times.

The people that actually do the work to make the product that makes the company money... Those people are FAR more important than a manager that manages managers.

CEO/Owner - > department managers. THAT IS ALL THAT IS NEEDED. everyone in between are dead weight parasites.

Not likely. One of the large costs with any of these missions is launch. With SpaceX pushing re-usable systems, and about to drop their prices a great deal in about 3 years, it will make missions like this possible.
In addition, keep in mind that Musk is now looking at building a satellite factory. Once he starts that, he will be after all sat manufacturing to make them cheap. While this is an airship, the guts will be satellite based.

The two times I used a towncar service it was great. Typically they know the best routes through the city and they pay attention to rider comfort above all else, they do not drive like maniacs and intentionally slow down smoothly. The towncar I used in Chicago 4 years ago did not even have a GPS, he knew the city, something that is rare now.

"or focus on rich people who don't want to travel with unprofessionals."

WE have always had that, It's called hiring a town car. In any town you can make a call and hire a personal drive in a nice BMW 5 or 7 series or Lincoln or other luxury car to drive you everywhere you want and be at your beck and call.

And during "peak uber" pricing, it's cheaper to call a town car company and ride in class instead of some fat guys prius.

A lot of that is directly coupled to the health of the rest of the body. Most old people eat like crap and just sit there. Look at highly active fit old people and you notice that they are not suffering the same effects. Old farmers that are well into their 80's that are still working their farm daily heal as fast as their 40 year old self.

Sentient plasmoids are a gas.

Working...
