Air Rabbit. I for one thoroughly enjoy reading (and learning ) from your posts. But please break up the large amount of text with appropriate paragraphing. This contributor's eyes reading through trifocals start to glaze over after being forced to read line after line without a break. I wouldn't be surprised if others echo my thoughts but are too kind to say something. The pity is you write such thoughtful stuff and yet some may turn away from it due eye fatigue. No offence intended.
