DO NOT KNOW
but it is a healthy addiction
Obviously it has done massive damage to the author of the OP.
is (Singluar, and should be "Is", start of a sentence) chess addictive (Had this ended the sentence, fine, but given the context, missing article, insert "an" between chess and addictive) sports (Plural reference to a sentence that started out with a word that implies singular as "are" would be plural.)
Therefore, let's try this again. Topic should read "Is chess an addictive sport?", but rather, in the case of the OP, it's a brain-damaging sport!
how to recover and come out of this addiction?
what are the withdrawl symptoms..
