I think this could mean that the reason women don't experience as much cognitive decline in later years is because their brains are effectively younger, and we're currently working on a study to confirm that."

Elderly volunteers, with an average age of 68, were recruited to the study and assigned either an eighteen-month weekly course of learning dance routines, or endurance and flexibility training. Both groups showed an increase in the hippocampus region of the brain. This is important because this area can be prone to age-related decline and is affected by diseases like Alzheimer's. It also plays a key role in memory and learning, as well as keeping one's balance.While previous research has shown that physical exercise can combat age-related brain decline, it is not known if one type of exercise can be better than another. To assess this, the exercise routines given to the volunteers differed. The traditional fitness training program conducted mainly repetitive exercises, such as cycling or Nordic walking, but the dance group were challenged with something new each week. Dr Rehfeld explains, "We tried to provide our seniors in the dance group with constantly changing dance routines of different genres (Jazz, Square, Latin-American and Line Dance). Steps, arm-patterns, formations, speed and rhythms were changed every second week to keep them in a constant learning process. The most challenging aspect for them was to recall the routines under the pressure of time and without any cues from the instructor."
These extra challenges are thought to account for the noticeable difference in balance displayed by those participants in dancing group. Dr Rehfeld and her colleagues are building on this research to trial new fitness programs that have the potential of maximizing anti-aging effects on the brain. "Right now, we are evaluating a new system called "Jymmin" (jamming and gymnastic). This is a sensor-based system which generates sounds (melodies, rhythm) based on physical activity. We know that dementia patients react strongly when listening to music. We want to combine the promising aspects of physical activity and active music making in a feasibility study with dementia patients."
Use Chamomile Tea Ice Cubes To Freshen Up Tired Looking Skin. Brew a strong pot of chamomile tea (about 1.5 cups water with 1 teabag), allow to cool 10 minutes or more and then pour into ice tray and place in freezer. Once frozen, wrap the tea cube in a thin cloth or washcloth and apply to pimples, puffy under eye skin, sun-kissed skin, or irritated skin for a quick skin toner pick up. You only need to apply for a few seconds to a minute per area.
Dr Rehfeld concludes with advice that could get us up out of our seats and dancing to our favorite beat.

"I believe that everybody would like to live an independent and healthy life, for as long as possible. Physical activity is one of the lifestyle factors that can contribute to this, counteracting several risk factors and slowing down age-related decline. I think dancing is a powerful tool to set new challenges for body and mind, especially in older age."
This study falls into a broader collection of research investigating the cognitive and neural effects of physical and cognitive activity across the lifespan.

Set boundaries and stick to them. I find that most people know they “should” incorporate more self-care, but their lives are moving so fast that it’s challenging to slow down. Carve out an hour of alone time to make two lists: things in your life that give you energy and are life-giving and things in your life that drain you. Figure out which draining activities you have control over and start making an action plan of how you will reduce time spent on these activities — set boundaries, say NO.
