72 minus 8 = 64 years I have been playing. Have been playing bridge for 63 years.
how long have u been playin

since I get little sleep and thus [theoretically] have more time for chess you might say 83 years rather than 64 years?

Since school time, around 1948, so some 65 years.
Let's ask Narayanansri, born december 1932, he is anyhow 1 1/2 years older than I am !

I have been playing chess for about 2 years and 3 months. I posted a blog saying how I learned chess here.
