One of the top political issues of the day is how to combat young people not being active anymore.
It is almost impossible to divorce sport from politics, but sport is such a positive factor in today's society - there is nothing else which will bring so many people together in that atmosphere.
Success in sport is based on you thinking you are doing something to gain that edge, but if I wanted that little bit extra, I would go and run up sand dunes at Merthyr Mawr.
It's important for me that I stay in shape, although each year it gets a little harder.
I had jumped about 6.40 metres with no training, no run-up, and certainly no skill, when this big, good-looking guy came up to me and told me I could be great.
You can exercise right through to your 60s, 70s, 80s and even 90s.
I still do cardiovascular exercises, aerobic exercises, and then strength training, as it's important to keep your muscle strength, as every decade you lose about 10% of this.
People need to have clear goals about why they are exercising, and they should consult a fitness expert to find out what kind of exercise is suitable.
We have to harness the Olympic experience and this inspiration young people have to get into sport.
When you win an Olympic gold, it is such a powerful feeling that stays with you for the rest of your life.
I felt I was never going to beat Igor Ter-Ovanesyan or Ralph Boston because they were the joint world record holders.
