Got a complimentary 3 step health check from owell. Nice thing is they don’t need needles or something to poke to test your blood sample.
They used a small device that wrapped around your finger which checks for your body oxygen level and pulse rate. It also checks your vascular age.
Then they put olive oil over ring finger. and they put into the microscope to check. If you like to see photos you can go to the link below.
