- Over time, needing more of the drug to get the same effect
- Making certain that you maintain a supply of the drug

- Not meeting obligations and work responsibilities, or cutting back on social or recreational activities because of drug use
- Doing things to get the drug that you normally wouldn't do, such as stealing
- Driving or doing other risky activities when you're under the influence of the drug
- Focusing more and more time and energy on getting and using the drug
- Failing in your attempts to stop using the drug
- Experiencing withdrawal symptoms when you attempt to stop taking the drug
But does the running addiction matter? It may bring my running career to an earlier end. I may be getting around on a walking stick by the time grandchildren arrive. My legs may not tolerate the hiking and cycling adventures still on my bucket list. It may dominate my social life. All of these things do matter, but others matter more.
My father is now a nursing home resident with a quality of life I have no wish to emulate. His fate has reinforced a desire to live life to the full while I have the means. I'll be 65 in six weeks and there are many ailments that could claim me in the years to come. I only have to look around my demographic. My legs can't be the only thing wearing out.
The last six months of running has given me rewards (highs) that I thought had been consigned to history. It makes me feel alive and younger. I believe that more may be achieved with determination and good management, and I want to see how far I can go.
