Thank you for checking out our simple web page. We took '40 seconds test' after testing it with few people of different ages. Initially thought of doing 60 seconds, but it was hard for older people and for those with a sedentary lifestyle. So chose 40 seconds, which shows a good lung capacity than most people. Still it's hard for some people to meet that time, as you can see from some of the comments here.
