Your suggestion, IMO, needs to apply to EDIG. If not, your post is off topic.

I can suggest that EDIG tech, to my understanding, is able to sense that a person is under the influence of marijuana. Furthermore, I suggest that if that person was to fall (off a bike or chair ) while under the influence and as a result need assistance then a paramedic could be alerted to come to the rescue.  

I also have a more pressing question; could EDIG tech be able to determine if a person is in need of smoking or ingesting some marijuana? Wow, think of that? Could be a lot of people!

These are very pertinent questions and issues that if nurtured could indeed provide a bonanza of revenue for EDIG.

And no, I have not been smoking anything while coming up with this investment strategy for EDIG.
