Lifting Heavy Weights – These Reasons Still Apply for Me

Posted by Marcus Selle on Nov 28, 2012

While I absolutely love body weight exercises for their convenience and variety, there is no doubt that lifting some weights on a regular occasion can still provide tremendous benefits. Some people lift heavy weights for a purpose – body building, strength training, muscle definition, and more. Before I got my desk job(s), I was incorporating weight training on a much more regular basis and I noticed significant changes.

These changes are what I’d like to gain back as well as the following reasons:

Strength

I’ve never had much upper body strength and when I initially started lifting weights, I had to start off with lighter dumbbells around 8 to 10 pounds. As I became stronger, I worked my way up to 15 pounds. When you stay consistent, you will be amazed at how you progress. There is also something empowering about being able to lift a heavier weight.

Plants and herbs hold a tremendous amount of energy and beneficial compounds within their cells. But how do you access that? Ingesting raw plant materials is one way of tapping in, but it’s not practical to eat 3 pounds of spinach or 2 dozen apples to obtain the enzymatic benefits or aromatic constituents. The useful parts must be isolated and concentrated.

Healthful compounds in herbs or botanicals can be isolated from the cellulose and plant material when they are combined with a solvent. The desired parts “dissolve” within the solvent, leaving behind the bulk of the plant material, and are then ready to be concentrated. Alcohol and glycerin extractions are both effective but separate processes with different methodologies. For extraction or constituent preservation, glycerin performs better than alcohol.

If it isn’t one thing, it’s another. You’ll find that’s true for as long as you have children, even after they’ve grown. Your first taste of it will probably be when, just a few short weeks after baby has learned how to sleep through most of the night, she starts getting her first teeth in.

Teething usually starts when baby is somewhere around four months old. Ironically that’s just about the time baby can sleep for more than four hours at a time without waking up hungry.

For many parents, the first couple of teeth (usually the lower middle teeth) can be somewhat of a teaser. The first couple of teeth, because they are sharper, don’t cause baby quite as much discomfort as later teeth do, so babies usually don’t fuss quite as much with the first couple teeth.

Once the other teeth start coming in, be ready to spend some nights soothing the baby again. On a positive note, most babies won’t wake up every night like they did from birth to four months old. When they do wake up, however, they will be uncomfortable from the changes which they have no way of understanding, and will need lots of love and soothing.

Some parents find that the little tricks they learned to help baby fall back to sleep up until now just don’t work so well with a teething baby. Be prepared for this. After the first couple teeth, you’ll have no trouble recognizing the signs that baby is cutting a tooth. Here are some signs that indicate baby might be cutting her first tooth:

  • Problems sleeping
  • Slight fever
  • Cold symptoms, such as runny nose and coughing
  • Gnawing or biting
  • Drooling
  • Chin Rash (from the drooling, usually)
  • Pulling or rubbing cheeks or ears

If you suspect your baby is teething, and you’re having trouble soothing her and getting her to fall back asleep, there are some things you can try. Basically anything that puts counter pressure on the incoming tooth or chills the gums will offer baby some relief. Here are some things you can try:

  • Teething rings or toys. If you chill them in the refrigerator, so much the better.
  • Pacifiers. Again, try chilling one in the fridge or freezer for a little while before giving it to baby.
  • Bottle of cold water
  • Baby Orajel
  • Baby Tylenol

Different babies respond differently, so don’t be afraid to try different things to find out what gives your baby the most relief. She will be going through this several times between now and when she gets the last of her baby teeth (somewhere between two and three years old). Remember she will also need lots of cuddling, rocking, and attention in general while she’s cutting her teeth, too.

Optogenetics illuminates pathways of motivation through brain, Stanford study shows

Whether you are an apple tree or an antelope, survival depends on using your energy efficiently. In a difficult or dangerous situation, the key question is whether exerting effort — sending out roots in search of nutrients in a drought or running at top speed from a predator — will be worth the energy.

In a paper to be published online Nov. 18 in Nature , Karl Deisseroth, MD, PhD, a professor of bioengineering and of psychiatry and behavioral sciences at Stanford University, and postdoctoral scholar Melissa Warden, PhD, describe how they have isolated the neurons that carry these split-second decisions to act from the higher brain to the brain stem. In doing so, they have provided insight into the causes of severe brain disorders such as depression.

In organisms as complex as humans, the neural mechanisms that help answer the question, “Is it worth my effort?” can fail, leading to debilitating mental illnesses. Maj
