Why you might be feeling ‘more alert’ as you get older

The ovulation-tracking device ovulation tracking device (OVTT) on display at the Samsung Fair.

It can track the timing of the ovulation of your ovaries.

It uses a sensor that tracks the chemical signature of the sperm in your urine to determine how fast your ovulatory cycle is.

The sensor then sends a signal to a smartphone app that is then used to estimate your body temperature and the rate of your metabolism, which are used to calculate the amount of calories you need for day-to-day survival.

As a result, it can estimate your risk of having a heart attack or stroke in the future.

The app can also tell you how many calories you can eat each day, which is an important factor when planning a diet.

The device is currently available in Japan, where it is being sold for $399.
