SpaceX, a private company, NOT the government, NOT NASA, became the first organization to successfully launch a satellite into orbit using a recycled booster:
"A SpaceX Falcon 9 rocket recovered at sea from its maiden flight last year blasted off again from Florida on Thursday in the first successful launch of a recycled orbital-class booster, then capped the feat with another return landing on an ocean platform." - Reuters
This is the opening sonata of the symphony of the song singing of our ability to be a multi-planetary species. 
Why? because, "The potential is there for (an) over 100-fold reduction in the cost of access to space. If we can achieve that, it means humanity can become a space-faring civilization and be out there among the stars. This is what we want for the future," -Musk
NASA, Bezos, others; It CAN be done!
Congratulations SpaceX.

Soooo. I'm looking into upgrading the ol' career and the question, "please provide your salary requirements." is very difficult.
Do I provide a step up from my current salary at the current job?
Do I provide a salary based on my low consulting rate?
Do I use my high consulting rate?
If it is a job that has a national range between $50K and $90K but the potential employer doesn't provide a range, and I choose $100K am I out of the running? What about if I choose $35K, do they think I'm an idiot?
The best advice (from theMuse.com):
"You’ll likely come up with a range, and you should put the highest number in that range that applies, based on your experience, education, and skills. And yes, that’s a little aggressive—but bear with me.Next, I recommend writing “(flexible)” or “(negotiable)” next to your number. If you have room to do so—for example, in your cover letter—stress again that your salary requirement is flexible or negotiable and that there are so many working parts to compensation —benefits, job title, opportunities for advancement—that you’re certain you can find a way to satisfy both of you if you’re a good fit for the position."
I used this technique, starting high, for the first time yesterday. It was uncomfortable because I usually see things from the management perspective and aim to fit the job and make sure it is low enough, in the range that I researched, in order for me to get the job. This has worked very well before.
But for the job I tried this technique yesterday, I bet there is some laughter and shaking of heads!
That's OK, I'm trusting God and going for it. :-)

Currently, I use high dose Resveratrol, Omega 3s, and Curcumin as the core of my anti-aging protocol. This is a skimpy, but inexpensive supplement list. I keep my supplement list small and inexpensive so that I can afford to take these supplements in the VERY long haul (e.g. I have been taking Resveratrol since about 2005).
I recently read an article that has caused me to revise my supplement schedule.
​I am about to order a supplement called "Nicotinamide adenine dinucleotide," or NAD+. it "is a key cellular factor for intermediary metabolism. Originally defined as a molecular fraction (“cozymase”) that accelerated fermentation in yeast extracts, its chemical structure was resolved as a nucleotide sugar phosphate. The nicotinamide portion of NAD+ is the site of reduction-oxidation (redox) reactions, and its reduced form (NADH) serves as a key energy-transfer intermediate between different metabolic pathways"*
The recent article I read was about a startling discovery regarding reversing aging in mice. This was rreported in many locations, but this is from "Science Alert":
"They've shown that by giving a particular compound to older mice, they can activate the DNA repair process and not only protect against future damage, but repair the existing effects of ageing. And they're ready to start testing in humans within six months." 
That "particular compound" is NAD+.

Life Extension has been talking about this since about 2016, but I have only now decided that NAD+ has the three criteria that I desire most in an anti-aging supplement: 1) It has been clinically proven to slow aging 2) It has many beneficial broadband affects like anti-cancer, anti-diabetes, etc, and 3) It is inexpensive.
LEF has a preparation called "Optimized Resveratrol with Nicotinamide Riboside" that I will start buying in bulk to replace my normal Resveratrol supplementation.
it contains:
"NIAGEN®, a novel nutrient shown to support mitochondrial health and promote longevity pathways. This formula provides 100 mg of NIAGEN® nicotinamide riboside—an amount equivalent to almost 667 cups of milk. Optimized Resveratrol with Nicotinamide Riboside also contains specific compounds in berries, such as pterostilbene and fisetin, which researchers say work in synergy with resveratrol to "turn on" the body's own longevity genes."

I am also soon, going to look into AMPK activators. They are supposed to be anti-aging and promote fat metabolism,

I'll let you know how it works in a couple of decades. ;-)
