Hope can be incredibly destructive when your heart is broken. Heartbreak is a master manipulator. The ease with which it gets our mind to do the absolute opposite of what we need in order to recover is remarkable.

One of the most common tendencies we have when our heart is broken is to idealize the person who broke it. We spend hours remembering their smile, how great they made us feel, that time we hiked up the mountain and made love under the stars.

All that does is make our loss feel more painful. Yet we still allow our mind to cycle through one greatest hit after another, like we were being held hostage by our own passive-aggressive Spotify playlist.

Accuracy of Fossils and Dating Methods

Laughter Heartbreak will make those thoughts pop into your mind. And so to avoid idealizing, you have to balance them out by remembering their frown, not just their smile, how bad they made you feel, the fact that after the lovemaking, you got lost coming down the mountain, argued like crazy and didn't speak for two days. What I tell my patients is to compile an exhaustive list of all the ways the person was wrong for you, all the bad qualities, all the pet peeves, and then keep it on your phone.

Laughter And once you have your list, you have to use it. When I hear even a hint of idealizing or the faintest whiff of nostalgia in a session, I go, "Phone, please. But they were not, and neither was the relationship. And if you want to get over them, you have to remind yourself of that, frequently.

None of us is immune to heartbreak. My patient Miguel was a year-old senior executive in a software company. Five years after his wife died, he finally felt ready to start dating again. He soon met Sharon, and a whirlwind romance ensued. They introduced each other to their adult children after one month, and they moved in together after two.

When middle-aged people date, they don't mess around. But the night before their first anniversary, Sharon left him. She had decided to move to the West Coast to be closer to her children, and she didn't want a long-distance relationship.

Miguel was totally blindsided and utterly devastated. He barely functioned at work for many, many months, and he almost lost his job as a result. Another consequence of heartbreak is that feeling alone and in pain can significantly impair our intellectual functioning, especially when performing complex tasks involving logic and reasoning. It temporarily lowers our IQ. But it wasn't just the intensity of Miguel's grief that confused his employers; it was the duration. Miguel was confused by this as well and really quite embarrassed by it.

Heartbreak shares all the hallmarks of traditional loss and grief: Forty percent of people experience clinically measurable depression. Heartbreak is a complex psychological injury. It impacts us in a multitude of ways. For example, Sharon was both very social and very active. She had dinners at the house every week.

She and Miguel went on camping trips with other couples.

Although Miguel was not religious, he accompanied Sharon to church every Sunday, where he was welcomed into the congregation.

Miguel didn't just lose his girlfriend; he lost his entire social life, the supportive community of Sharon's church.

He lost his identity as a couple. Now, Miguel recognized the breakup had left this huge void in his life, but what he failed to recognize is that it left far more than just one. And that is crucial, not just because it explains why heartbreak could be so devastating, but because it tells us how to heal. To fix your broken heart, you have to identify these voids in your life and fill them, and I mean all of them. The voids in your identity: The voids in your social life, the missing activities, even the empty spaces on the wall where pictures used to hang.

But none of that will do any good unless you prevent the mistakes that can set you back, the unnecessary searches for explanations, idealizing your ex instead of focusing on how they were wrong for you, indulging thoughts and behaviors that still give them a starring role in this next chapter of your life when they shouldn't be an extra. Getting over heartbreak is hard, but if you refuse to be misled by your mind and you take steps to heal, you can significantly minimize your suffering.

And it won't just be you who benefit from that. You'll be more present with your friends, more engaged with your family, not to mention the billions of dollars of compromised productivity in the workplace that could be avoided.

So if you know someone who is heartbroken, have compassion, because social support has been found to be important for their recovery. And have patience, because it's going to take them longer to move on than you think it should.

And if you're hurting, know this: But you do have weapons. In the past years they have not found any fossils that Darwin would not have expected. Darwin and his contemporaries could never have imagined the improvements in resolution of stratigraphy that have come sincenor guessed what fossils were to be found in the southern continents, nor predicted the huge increase in the number of amateur and professional paleontologists worldwide.

All these labors have not led to a single unexpected finding such as a human fossil from the time of the dinosaurs, or a Jurassic dinosaur in the same rocks as Silurian trilobites. Scientists now use phylogeny, mathematics, and other computations to date fossils.

Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record. These demonstrate that, of course, we do not know everything and clearly never willbut we know enough.

Today, innovative techniques provide further confirmation and understanding of the history of life. Biologists actually have at their disposal several independent ways of looking at the history of life - not only from the order of fossils in the rocks, but also through phylogenetic trees. Phylogenetic trees are the family trees of particular groups of plants or animals, showing how all the species relate to each other.

Phylogenetic trees are drawn up mathematically, using lists of morphological external form or molecular gene sequence characters. Modern phylogenetic trees have no input from stratigraphy, so they can be used in a broad way to make comparisons between tree shape and stratigraphy.

The majority of test cases show good agreement, so the fossil record tells the same story as the molecules enclosed in living organisms. Accuracy of dating Dating in geology may be relative or absolute.

Relative dating is done by observing fossils, as described above, and recording which fossil is younger, which is older. The discovery of means for absolute dating in the early s was a huge advance.

The methods are all based on radioactive decay: Fossils may be dated by calculating the rate of decay of certain elements. Certain naturally occurring elements are radioactive, and they decay, or break down, at predictable rates. Chemists measure the half-life of such elements, i. Sometimes, one isotope, or naturally occurring form, of an element decays into another, more stable form of the same element.

  • Radiometric Dating and the Geological Time Scale

By comparing the proportions of parent to daughter element in a rock sample, and knowing the half-life, the age can be calculated. Older fossils cannot be dated by carbon methods and require radiometric dating. Scientists can use different chemicals for absolute dating: The best-known absolute dating technique is carbon dating, which archaeologists prefer to use.

However, the half-life of carbon is only years, so the method cannot be used for materials older than about 70, years. Subtle differences in the relative proportions of the two isotopes can give good dates for rocks of any age. Scientists can check their accuracy by using different isotopes. The first radiometric dates, generated aboutshowed that the Earth was hundreds of millions, or billions, of years old. Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates.

Age estimates can be cross-tested by using different isotope pairs. Results from different techniques, often measured in rival labs, continually confirm each other. Every few years, new geologic time scales are published, providing the latest dates for major time lines.

Older dates may change by a few million years up and down, but younger dates are stable. For example, it has been known since the s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old.

Repeated recalibrations and retests, using ever more sophisticated techniques and equipment, cannot shift that date.

It is accurate to within a few thousand years.

The strict rules of the scientific method ensure the accuracy of fossil dating. Conclusion The fossil record is fundamental to an understanding of evolution. Fossils document the order of appearance of groups and they tell us about some of the amazing plants and animals that died out long ago.
