Energy and Clear Thinking
Size: 90 Count (Pack of 1)
Great product. I use various forms of magnesium for different things . This form was suggested for clearer thinking and energy, and it delivers! I use it in the AM and it helps keep me energized I do think it varies by person how it affects you though as some folks get drowsy w/ it. Just a heads up to test on a weekend perhaps. I won't be without it now!

Capsules Are Too Large and Have a Strong Plastic Smell
Size: 90 Count (Pack of 1)
I’ve purchased this product twice, but the capsule design is a big downside for me.
The capsules are very large and difficult to swallow. On top of that, there is a noticeable plastic-like smell from the capsules, which is quite distracting and unpleasant. It makes taking them every day uncomfortable.
The product itself may work as intended, but the capsule size and odor seriously affect the overall experience. I wish they would improve the capsule material or offer a smaller or odor-free option.
If you are sensitive to smells or have trouble swallowing large capsules, keep this in mind before buying.

An Excllent Guide to Ancient China

Anyone who has even the slightest interest in ancient Chinese history will find at least part of this book enjoyable. Reasons for as much include dedicated research, engaging prose, and a commitment to ensuring all readers can access this work. This one is not to be missed!

....limited information about how the average person...
Format: Kindle
Coverage of the earliest period does (of necessity through lack of records?) encompass rather a lot of conjecture and assumptions.
There's certainly a good coverage of the period - but it can become rather dry as it cycles through successive rulers.
There's limited information about how the average person lived during the time covered.
Tended to skim past extended descriptions of fairy tales of ancient beliefs and convictions.
The book occasionally reverts to mentions of much later personalities (such as Freud) and comparing them to characters of ancient China!
