Thank you Cat and Pistol Pete (and Dr Doug...LOL! Yeah - I caught that, too!) that is WONDERFUL to know! I had given Ike a supplement called "Young At Heart" that contained Choline, and also noticed him acting "brighter and clearer". But YAH also has additives to help with "elderly wasting" which Ike certainly had. Now, I'm seeing that same vague look in Jack's eyes at times (he's 13) - but he's at a perfect weight, certainly doesn't need to gain. I think I'll give it a try! Well, I mean JACK will give it a try and his sex life isn't much, either ;-)
