These are all the possibilities I have on my apple computer to have efficiency. I have the same possibilities on my Windows computer. It just depends which computer I happen to be working with. I also have an iPhone, which is coupled with my apple computer, so what could possibly go wrong? I have learned over my computer years that nothing is perfect. Computers do not live for ever, although we are led to believe they do. I have lost a few things over the years in mysterious ways and have set priorities.
Most important are dates and times that must be maintained with no exceptions. One of these are my MS injections which I should apply every second day and where I inject is also important. It is not good permanently injecting in the same place as that could cause an infection. And so it goes: right and left stomach, right and left leg, right and left arm and right and left in the most sensitive and difficult parts to reach (no details). If I keep this routine, no problem. My reminders are important, no matter where they are, all electronically guided with a peep, a lit up screen and whatever and this in my Apple appliances. What happens if your computer organisation goes on strike. Suddenly the reminders disappear. Yes, it happened to me once on my telephone and the iPad and computer followed, hanging all in the same cloud. I went for a search in Internet and found that this is a possibility. I managed to re-instate my reminders file, but there were no more reminders in it.
Unfortunately I depend on this organisation and possibilities are not my solution. I have my solution for this inefficiency which could happen. I bought myself a wonderfully bound notebook and when an injection is due I enter the date and place for the next injection. These injections do not cure, there is no cure for MS, but they stop the rapid progression of the illness.
Never rely on a computer, they have human qualities of not always being infallible, after all they are machines made by humans. I always have a backup in good old fashioned writing. A lost telephone number is not so bad, you find it somehow. Just saying.
