Seizure First Aid. 

Learn it. Share it. Know it. Use it. 

100% correct medical information on tumblr for once; also consider calling 911 if you don’t know how often the person has seizures and ESPECIALLY if the seizure has lasted 5 minutes or more (which is why the watch is critical)

This is so important!
