Nutrition
From Edward Miller:
Most people are deficient in multiple vitamins and minerals, and you guys on the farm are no different. From my knowledge of you, I speculate that you guys are deficient in iodine, B vitamins, selenium, carnitine, carnosine, and probably more.
Hormones also greatly effect how you feel, and perhaps your greater focus is related to this. As people age their levels of melatonin, DHEA, testosterone, coQ10, and many other things decrease. Some recommend trying to boost testosterone and DHEA. Exercise (high intensity interval training) and proper nutrition can help slow the decrease. Also, you can take DHEA pills just like melatonin, but it isn't as cheap... almost nothing is as cheap as melatonin. There are some stuff to help with testosterone too, which could restore youthfulness, such as DIM and I3C, broccoli extracts. Straight testosterone requires needles and a prescription, and I wouldn't recommend that.
As for food, keep eating lots of turmeric, garlic, and other spices. Hopefully you will be getting lots of berries chock full of antioxidants soon. Beets, Kale, and other things you are growing are sort of super foods. It'd be nice to get some broccoli. Since you eat a lot of greens, you probably get enough vitamin K.
Try to drink lots of green tea. The Life Extension Mix that I gave you comes with green tea extract, and you can buy it separate, but there is nothing like a good cup of tea.
Poor man's supplements:
Melatonin - unbelievably cheap, sleep-improving, antioxidant, life-extending supplement!
Vitamin D - you spend a lot of time in the sun, but people have still been known to be deficient in sunny areas, and it is dirt cheap
Omega 3 - Anti-inflammatory, mood stabilizer, and wonder supp! Pretty cheap in bulk... liquid is even cheaper if you can stomach it.
TMG - Cheap B vitamin which lowers homocysteine
NOW ADAM Men's Multivitamin - is usually considered the best poor man's multi, and has the proper zinc and magnesium levels for men.
Low Dose Aspirin - If you have a history of heart disease in your family, this is a cheap way to help it
Medium range supplements:
Carnosine - essential glycation-breaker, especially necessary during low meat-consumption periods... eggs and milk dont have it
Acetyl L-Carnitine - Awesome energy-boosting, life-extending, wonder nutrient! (especially during low meat consumption periods)
Lipoic Acid - Protects mitochondria... especially good to take with carnitine which revs up your metabolism
Piracetam - Safe intelligence enhancing amino acid which goes great with DMAE, a cheaper form of choline.

If you want more information on dosages, let me know. Many people concerned with price use iherb.com for everything, but I am an lef.org member so I use that. There are other sites you can compare price with like vitacost.com or amazon.com
Though dosages and frequency could change the price considerably, A yearly multi would be about 100 bucks.
Buying in bulk with Jeremy, Ben, and anyone else could potentially reduce costs considerably
This was the best price on Google Shopping, the seller has a 4 star rating: http://www.healthsuperstore.com/p-now-foods-adam-60-tabs.htm
It would be best to buy the entire year's supply at once to save on shipping.
