Thanks for the two posts this morning Terry. They are very enlightening and provide more examples of how you keep TI fresh and new and have been doing so for a long time.
At age 74 I have benefited from many of the aspects you speak of. In the happiness/mental field and of course the swimming field . The last year I have noticed some slippage in my mental accuity and thank my lucky stars that I have stayed active and the resulting sliipage has been minimized. All the same the slippage is disconcerting so it is serendipitus that you bring this subject to our attention and it gives me a gentle kick in the butt to play harder (as in pay attention) with these ideas.
May we swim with ease at the speeds we choose.
