They say it can take from minutes to hours. But, who are ‘they’? ‘They’, who you can see and hear and are on the banks of that big body of water. ‘They’ are standing on the hard surface, while you are trying to grab onto something, or find a footrest somewhere. However, you can’t because you’re drowning, and you don’t want to. Perhaps, ‘they’ also don’t want you to die.

In a recent study, researchers from the Indian Institute of Technology (ISM) Dhanbad have developed a blood glucose sensor to monitor blood sugar using light. It can measure a wide range of values of blood glucose, between 10 to 200 mg/dl, say the researchers. The average blood sugar level in healthy adults when fasting is between 70 to 120 mg/dl.
