I would instead point to a changing culture where the work ethic barely exists. My present college students profess lofty career goals that would require postgraduate degrees yet they are no-shows in the classroom, adamantly refuse to study or come to class prepared and believe they should be pushed along because, frankly, that is what I believe their previous academic experiences were like. Scholarships often go unawarded but few want to 'bother' writing the required essay. The local newspaper in my semi-rural area is replete with articles citing employer complaints that they can't find employees willing to do the job.

Again, they call for adults to complete at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous activity every week, along with strength training twice a week. ...
Any physical activity, no matter how brief, including walking up stairs or from the car to the office, provides health benefits, according to the new guidelines, and counts toward exercise goals.

Using these parameters, “it will be much easier” for people to accumulate the desired 150 weekly minutes of moderate activity, says Adm. Brett Giroir, the assistant secretary for health at H.H.S., who oversaw the development of the formal guidelines. ...
Despite 10 years of hearing that we should be moving more, few of us are.

Only about 20 percent of American adults meet the existing recommendations, and a third never work out at all, statistics show.

As little as 20 seconds of brisk stair climbing, done several times a day, might be enough exercise to improve fitness, according to a pragmatic new study of interval-style training. ...
The exercisers reported to the physiology building’s stairwell. There, the researchers directed them to warm up with a few jumping jacks, squats and lunges and then hurry up 60 steps — three flights of stairs — as quickly as they could, one step at a time, while using the guardrail for safety. These ascents lasted about 20 seconds.

And that was the workout. The volunteers repeated these abbreviated exercise snacks twice more that day, usually at lunch and again in the afternoon, for a total intense exercise time of about a minute.

By the end of six weeks, the exercisers had increased their aerobic fitness by about 5 percent. They also showed improvements in leg power and could generate more power while cycling.

Most any stair-climbing routine, experts say, is a healthy step, literally, toward achieving the recommended level of physical activity for adults, according to the American College of Sports Medicine and the American Heart Association. ...
“It’s not all or nothing,” said Carla Sottovia, an exercise physiologist at the Cooper Fitness Center in Dallas. “Short bouts of exercise, like climbing stairs, certainly help. It all adds up.”

When you’re free from the switch, it’s immediately obvious how much voice-controlled lights, again, make a lot of sense.
It even frees you to turn off lights in rooms you’re not in. In the old days, if you remembered leaving the lights on downstairs, you would have to stop what you were doing, run down the stairs, flip the switch and trudge back up. With a cheap smart speaker in your bedroom — or even the voice assistant on some phones — you can control any light in the house without going anywhere.
