I am sorry that Keith's was so tired during the cruise. I have used a chair/cane on days when I have felt a bit shaky. It is light weight and provides a great place to sit down when you need to. However with my size it usually becomes more like a suppository. <VBG>
I hope that Keith can get his strength back. This can be as much of an incentive as a let down.
One question though. Are you sure he didn't become light headed after he saw the bill for what you bought in the shops in Puerto Villarta? <VBG>
Take care of both of you and thanks for the review.
