yes, memory is cheap and big and easy to use and copy and transport
these days.
Amazing the development for us old computer people who had
watched it from the beginning

I also have a big file, sort of diary, where I write all my small symptoms
and how I slept and other medical things and observations.
Way too big and too scetchy to show it to doctors who have not
the time to read it.
But it's good for keyword-search, e.g. when you want to know
when a new symptom first appeared.
Then I use it to make charts of my weight over time, or frequency of
certain symptoms over time etc.
