As a doctor my notion of coma,is harbinger of a full stop i.e.death; colon is part of gut but definitely I have not read about semi-colon: colonectomy puts a patient on a tube!
Thanks Youngman at least you have spared time to read my long sentence, for ornamentation which knowingly I had written long with maximum characters permissible by Rediffboard, in defence of Dr.URA who is a very senior friend of me (I am incidentally 53 today as per Hindu calendar!). The spell check I did today and though I had two spelling mistake "dialect," and "milieu," the long sentence was not shown fragmented and was OK grammatically though English is fourth tongue for me and naturally my mistakes deserve omission.
