That Guest, A Regular, is maybe not very regular. I say read lots more 'Cat threads. A good laugh gets more oxygen in your lungs and bloodstream. Perks you right up.   Then there's the attitudes -- sharing knowledge, doing good things for each other, encouraging others to uphold standards of decency to each other and the planet...
Especially the sharing of music. I have a theory: the slow air "Planxty Erwin" is one of surpassing beauty and peace. Every playing of that tune adds to the aggregate of those qualities in this world. You may know some tune(s) that impresses you that way. Share that tune on a regular basis. You will be doing something to help others on the planet to experience Peace and Beauty. Eventually critical mass will be reached. There are others in all "walks of life" who are doing some version of this exercise.   There are cooks, builders, teachers, painters, parents -- all finding the epitome of Peace and Beauty somewhere in their purvue and spreading it around. And don't forget the oxygenating laugh.

Also, just for safety's sake, get a thorough physical, to rule out anything that might be beginning to deteriorate.

Maintain basic good health, laugh, share music -- and keep in touch with Mudcat. These folks have a lot of experience-based knowledge. Access to such is always beneficial.   This prescription can be filled and refilled right here. Any dosage you find successful. Make a follow-up appt. at the nurses' desk on your way out. Put your clothes back on.   See you soon.   Dr. Tw
