I am 91 years old and without my smart watch and phone my to do list would not exist. I can’t read my writing to begin with but it takes me a minute to write a couple of words after a ten minute search for my Calendar. My watch is always on my wrist yes even at night when I remember many things to do. It takes me 20 seconds to say to my watch “reminder 9 am call the Doctor. At 9 am it buzzes me and shows the note. I can then tell it to call the Doctor and it does. There is no limit to the items you can add and included or how distant you want to date items. And unlike me it has perfect memory? I am already somewhat handicapped without my smart watch and phone I would need a full time physical assistant. Incidentally, I dictated this message into my iPad and electronically copied it into your space. We seniors need all the electronic help we can get. Do you know if I fall and become unconscious my watch will dial 911 and tell them where I am? It will also tell me my heart rate, blood oxygen level and take and take a ECG. OH, yes it keeps perfect time. Many many useful things.
