Don't be fooled by the age. I am still playing tennis, albeit I do prefer clay courts these days and I hope to keep playing for many years. People say I look younger than my age and I am grateful for good genes. And yes, I am actually 78 until March, no younger, no older. I am a curious, active person. It is important to be stimulated and challenged. I have various interests and pursuits that keep me busy and give me something to look forward to.
