So -- your
"A lunar Distance is the distance to the moon or approximately 238,900 miles"
in #9, wasn't too shabby... '-)
(H/T to my Mac's handy "Units Converter Widget"...)
The mean semi-major axis has a value of 384,402 km (238,856 mi). The time-averaged distance between Earth and Moon centers is 385,000.6 km (239,228.3 mi). The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).
Interesting... My mind has been in a fog for a few weeks and yesterday it was hitting bottom. Dr’s could not figure it out so I went to the medical and neuroscience texts and figured it out late yesterday.
It’s amazing how a Thiamine deficiency (not alcohol related) can screw with the physical body and mind.
Corrected it, along with the related fatique, ataxia, acidosis and glucose intolerance. Bingo... now I feel energized like I am on speed and my mind is the clearest in many weeks.
I thought old age was catching up to me with fatigue, systemic infections, dizziness, brain fog, and finally losing my spacial memory which has been a lifetime strong point. While I love the Dr’s, it is best to do your own medical research.
