Next time you put on that smartwatch, think about this...
Researchers from Mount Sinai have found Apple Watch can detect small changes to a user's heartbeat.
The change in heartbeat may indicate a person has coronavirus up to a week before they feel sick.
The PGA Tour started using the technology and it may have helped player, Nick Watney detect he was positive for COVID-19.
What do you think? Do you believe this really can help detect covid-19? Or is this a reach?
