Susie I think you have many more healthy years in you. We all tend to concentrate on a measure of our living, years, instead of experiences. The reality is we have no idea when our candle will switch off. Some people get warning,s. Others simply don't wake up.
Enjoy your writing. Enjoy your little caravan. Enjoy all the feedback from your Medium friends.
Life is what it is, joyful, fearful at times, eventful, full of wonder and awe. It's ours only for a time, and then we join the angels. :)
