Swimming in Outdoor Pool

This September I swam more in a pool then in the ocean! Having a month-ticket to a nice neighboring pool makes it easier, and there was too much seaweed along the coast this year after the first hot weeks of Fall. 

In the pool I used to make around 60 short lengths (25 yards) first, but then my friend pro-swimmer suggested I should do 66 (one mile, or 1650 yards, or 1.5 kilometres), and I switch to a swimmer's mile a day. I turn like I do in open waters, barely touching the walls and it takes me the whole 45 minutes of non-stop breaststroke to finish :) You may laugh about it, but for somebody whose main sport in youth was piano I am doing pretty nicely.

I am looking forward to double the distance if I have a chance to continue in this open air heated pool (~80F) for months, but I am not sure that staying in the chlorinated water for one and a half hours will be very pleasant, in the ocean it is no problem till 2-2.5 hours, but in the Pacific I get cold by the end.

A few days ago I bought a waterproof solar training watch with a timer and 120 laps counting by pressing a button, so now I don't need to keep numbers in my head and can go into a happy trance :)

Vitamin B12 Cobalamin

Vitamin B12, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism.

No fungi, plants, nor animals (including humans) are capable of producing vitamin B12. Only bacteria and archaea have the enzymes needed for its synthesis. Proved food sources of B12 are animal products (meat, fish, dairy products). Some research states that certain non-animal products possibly can be a natural source of B12 because of bacterial symbiosis.

B12 is the largest and most structurally complicated vitamin and can be produced industrially only through a bacterial fermentation-synthesis. This synthetic B12 is used to fortify foods and sold as a dietary supplement.

Vitamin B12 consists of a class of chemically related compounds (vitamers), all of which show pharmacological activity. It contains the biochemically rare element cobalt (chemical symbol Co). The vitamer is produced by bacteria as hydroxocobalamin, but conversion between different forms of the vitamin occurs in the body after consumption

B12 aids in lowering homocysteine levels and may lower the risk of heart disease. 

Recommended daily amount: 2.4 mcg

Example sources: fortified cereals, doenjang and chunggukjang (fermented soybeans), nori (seaweed).
