For me it's this year. I turned 74 this past spring. I stay active but am starting to lose some balance. Every time I bend down to mark my golf ball i feel like I'm going to topple over. I can no longer go up and down the stairs in our home with out having one hand free to hold onto the railing. Im not really complaining as I can still get out and play, I can no longer handle cold weather. However life is good for this old geezer. Praise God!
