I am a retired Senior and live alone.  Consequently, my biggest challenge is cooking for one.  I recently purchased a Wolfgang Puck 8 qt. Rapid/Pressure Cooker.  It is one of the best decisions I have made in years because it is electric & has a timer.  At my age, sometimes I get side-tracked and forget I have something on the stove or in the oven; now I don't have to worry about burning down the house.  Also, I can cook enough for a few meals and portion freezr it.  Works great for my life style!
