Slightly off topic, but I do not know where else I can post this.
If there is a subject that you want to keep up with, like PD, you can obviously Google every day, but that would be a pain. You can get Google to perform this continual process for you. Method:
Google the subject. In my case the subject is "Deep Brain Stimulation". The results are displayed as normal.
Choose to list Videos. It does not matter if you are not interested in videos.
Scroll to the bottom of the page where you will see the heading "Create alert." Click, then click on "Show options". Fill in details.
Google will email you when it finds something about your subject.
