<p>Physically active adults have higher concentration skills, which may help maintain memory and combat dementia. A study by researchers at Northwestern University Feinberg School of Medicine found that sedentary lifestyles directly contribute to the decline in cognitive abilities and quality of sleep as we age.</p><p>In this study, men and women ages sixty-seven to eighty-six, who were functionally independent, participated in a two-week study involving a regimen of thirty minutes of mild physical activity, thirty minutes of social interaction, and a final thirty minutes of mild to moderate physical activity. Sessions began with warm-up stretching and mild to moderate physical activity (walking or stationary upper- and lower-body exercises). The final period of mild to moderate physical activity included rapid walking, calisthenics, or dancing. A ten-minute cool-down concluded the ninety-minute regimen.</p><p>At the end of the two-week period, all of the participants demonstrated a 4 to 6 percent improvement in cognitive performance, and improved sleep quality (including deeper sleep and fewer awakenings).</p><a class="default-logo-link" href="/ebooks/613995-121-ways-to-live-121-years-and-more">See more</a>
<p>For travelers who are adventurous, budget-minded, free-wheeling and prefer flexible itineraries - but don't require the luxury or convenience of a cruise ship - the Alaska Marine Highway System (AMHS) provides an informal year-round public transportation alternative to taking a cruise. Dubbed the "poor man's cruise ships," the 11 state-owned ferries of the AMHS ply the waters of the Inside Passage, southcentral Alaska and southwestern Alaska, reaching the same ports - and more - that cruise ships do. Its coastal routes cover more than 8,000 miles, from Washington State north to ports near Anchorage and west to the Aleutian Islands. Though called a Marine Highway, it's like no other "highway" in the country, traveled by ship rather than by car. You can, however, take your car (if you have one) aboard any of the ferries for additional land touring along the way or after you disembark at your last stop. <br>
Alaska Marine Highway ferries<br>
<br></p><p>From the southern terminus in Bellingham, Washington, some 90 milesnorth of the Seattle airport, or from the Canadian departure point in Prince Rupert, B.C., the ferries pass by the lush, green rainforests of British Columbia and the glaciers, fjords and snow-capped peaks of Alaska's Inside Passage. Northbound travelers can make the journey from Bellingham (leaving on Fridays in summer) to Haines or Skagway at the northern end of the Inside Passage in a bit less than three days, not including any stopovers you choose to make. You can then connect to similarly beautiful Prince William Sound to the north and then west via Kodiak to the remote Aleutian Islands, though those ferry schedules are much more occasional. Along the way, you may choose to stop in tiny fishing communities and native villages as well as well known ports such as Ketchikan, Juneau, Sitka, Skagway, Valdez, Whittier, Seward and Kodiak. There are some 15 potential stops alone along the Inside Passage, and another 15 to the north and west. The Alaska Marine Highway System has been designated both a national Scenic Byway and, more recently, an All-American Road, one of just 27 "roads" - and only two in Alaska, the Seward Highway being the other - so honored in America. (To qualify, an All-American Road must have both national significance and one-of-a-kind features not existing elsewhere. Besides being the only maritime "road" in the national highway system, the AMHS is the longest byway in the United States.) Besides mountains, fjords and glaciers, wildlife are an integral part of the scenery on this highly scenic route: In the sea and air, watch for whales, orcas, otters, sea lions, harbor seals, Dall porpoises, bald eagles and seabirds. On land, watch for bears prowling on shore or mountain goats perched high on the cliffsides. </p><a class="default-logo-link" href="/ebooks/615458-cruising-alaska-a-guide-to-the-ships-ports-of-call-7th-ed">See more</a>
Phases, Cycles, and ScalesAdaptive<br> Cycles and How Systems Change
</p><p><br><br><br><br><br><br> Thresholds as discussed in chapter 3 are relatively easy to appreciate because most people have experience of some aspect of an ecosystem that has gone bad and stayed that way. It might be a stinking lake that was once a popular fishing spot, or an eroded landscape that was once an agricultural breadbasket. It might be an entire swath of towns like the Rust Belt in the United States where industries are no longer competitive, or a vast area like the Aral Sea that has become a biological desert. These places have crossed a threshold into a regime in which the controls (feedbacks) are different, and it wont be easy to return to the way things were.</p><p>There is a much higher likelihood of crossing a threshold into a new regime if you are unaware of its existence. This can easily occur because resilience (which, as we discussed in chapter 3, can be defined as the distance to a threshold) is a multi-faceted measure of a social-ecological system that changes over time.</p><a class="default-logo-link" href="/ebooks/569756-resilience-thinking">See more</a>
