I selected option 4 over option 3 - because most of the data concerning 3 is not big data - rather it is mapping and imagery which are Big Volume Data, but are not Big Data as such mapping and imagery is readily analyzed by GIS and imagery tools.

Agreed. Correlation is one thing, but causality is another. So much data analytics does not go beyond correlation.

A large degree of medical consultation can be handed over to machines. Already a significant percentage of people try to self-diagnose anyway with online resources. I am one of these - and you get good at it too. So especially for more routine consultations I don't see a problem. Many countries don't require prescriptions for many medications and...

It's easy to say Trump is dumb - stupid tweets, statements and lies.

This is where US public media got it so wrong for so long. Trump manipulates his base and will continue to do...

@PatriciaFalon I agree that the Fitbit is very useful. I wear mine almost 24/7 and discovered that i have a very low resting pulse - down to around 40 during deep sleep. At points during the day around 50. Fortunately all is Ok and is not uncommon with (some) athletes. So I am a big fan of tools such as fitbit for monitoring heart, exercise etc.
