 Cog·i·ta·tion [koj-i-tey'-shun]
– noun: Concerted thought or reflection; meditation; contemplation.
Kirt ['kərt ] – proper noun: RF Cafe webmaster.
These articles were originally known as 'Factoids,' but the title was changed
because of the multiple (and sometimes unflattering) definition of the word.
Note: There is also a huge collection of my topical 'Smorgasbord' writings
that might interest you as well.
These original Kirt's Cogitations™ may be reproduced (no more than 5,
please) provided proper credit is given to me, Kirt Blattenberger.
