I stared using a cane before I was 40--having been disabled by illness and surgery at age 21. I started a bit before I absolutely "needed" the cane so as to force myself to not be vain, as in--I'm too young a woman for this, it doesn't look good, etc. Let me say I love that cane and the mobility it gives me at 70. It is now my old dear friend (and I have many cute ones). I can imagine why you'd really enjoy some cruises. So, a question--have you ever tried the scooter? Would it be good--fun even--to use one in some low key situations to see if you like it? And/or maybe go on a short local cruise to see if that works before embarking on something more ambitious? However, I also understand the feeling that travel might be too much. There are ambitions I just don't have. I'm guessing you do have "sense." Consider what kind of compromises or strategies you'd feel ok about. Tell us how your thinking develops, if you feel like it.
