The sit-and-reach test

Some conclusions:

1. Youth and females have greater flexibility than elders and males (perhaps obvious).
2. For my group (33-year-old males) the 50-50 point by coincidence is '0 cm', i.e. touching one's toes. Meaning that about half cannot reach their toes (although 80% of young girls can!). 
3. As for my own story, I used to be 13 cms short of my toes. This meant that I was at about the 20% mark (4 out of 5 men could reach further than I could). BUT NOW, after weeks of exercise, I can exceed my toes by 7 cms - this means that I am over the 60% mark and only 2 out of 5 men can reach further than I can!
