Ups and downs of Life!

Some time I feel very much old, feeling tired of 85 yrs. It slumps down and make me idle. What could be the reason? Is it mental dead? or Physical bug?. Absolutely nothing.. These things are due to the toxins mobbing the mind..since over thinking.. I planned to stop touching computers atleast for a week....at least for a day(?..) .....at least for an hour(!!?)......at least...NO NO where is 'G', O' .... 'O' and .. 'G' then.... 'L' then... 'E' '.' 'C' 'O' 'M' and enter key....?
