Get yourself a dog. Especially a Rhodesian Ridgeback. They will demand enough attention and give back lots of emotional support so your trading day will be interspersed with emotional re-charges. Some say RR's are like little people in a dog's body. They are very affectionate and intelligent. Not to mention, strong enough to remove the limbs from any would be burgler.
I'm 99, and glad to be pushing a hundred. I can barelly control my bowel functions, and i'm proud of it. And by the way, i did mean walk on a nice beach, i have a house in San Diego. Now thats a walk. Eat your heart out.
I usually have either my 8 month old or my 2 year old sitting on my lap or crying to be held. Sometimes my 8 mo. baby will crawl under my desk and yank my mouse or keyboard under the desk. So when ever these events are not occurring... I am pretty relaxed.
