It makes perfect sense.
With our hypercharged careers, family responsibilities, keeping up with the news and working out -- who has the time to meet people anymore? What woman in her 50s really enjoys meeting strange men at bars? Most Internet "first dates" begin at bars. Still, the draw is strong. Everybody seems to know somebody who's met her significant other online. And then she found Ben -- only three hours away. What nobody really seems to tell you is that for every online dating success story, there are hundreds of failures: What we can learn about relationships from politically divided couples My situation is fairly typical.
After juggling two children and a demanding job, my first marriage ended in divorce. I had given it some hard thinking, but my relationship with my husband, which began when we were both in college, really couldn't make it for the long haul. So I opted out. About a year later, I encountered a friendly, good-looking neighbor, who had just recently become single. Howard became my second husband and the love of my life. That made it all the more crushing when he died of a brain tumor two years into our marriage.
Thus began a long period of mourning, in which I helped usher my two daughters into adulthood, and devoted more attention to my career. But I was awfully lonely. It didn't help that I went straight home from work every night and stayed in on weekends. Ronni Berke My friends would gently nudge me: Oddly, I'm a very social person. Why was I cutting myself off from the world?
My reasoning was this: If I don't do anything, don't "get out there," nothing bad will happen. As in no disappointment, no heartbreak. There's one problem with this line of thinking. Yes, if you don't do anything, nothing bad happens.
However, nothing good happens, either. So, seven years after my husband's death, I took the plunge. I signed up for online dating and even went to a speed dating session at a local bar. I approached online dating very seriously, enlisting help from close friends for my profile. It needed a dash of wit, a sprinkling of sass and an attractive photo. But not too much wit, and not too much sass. As for the photo: There's no such thing as too attractive.
After everything posted, I got a flood of responses from men. Not because I'm an exceptional catch, but because those who've been on the sites for a while tend to pounce on a new candidate. There were men who lived in other states and countries. I can't afford to see you. And Skype relationships are pretty two-dimensional.
Men who mentioned sexual details in their profiles. Yes, we get that sex is important, even in middle age. But this is just too much information! Men who were grammatically challenged.
3 Top Dos and Don'ts For Single Women Dating After 50
Either I'm not worth a coherent sentence or you are unable to compose one. Objects farther from the Sun are composed largely of materials with lower melting points. For comparison, the radius of the Sun is 0. Thus, the Sun occupies 0.
ESA Science & Technology: Solar Orbiter
Jupiter, the largest planet, is 5. With a few exceptions, the farther a planet or belt is from the Sun, the larger the distance between its orbit and the orbit of the next nearer object to the Sun. For example, Venus is approximately 0. Attempts have been made to determine a relationship between these orbital distances for example, the Titius—Bode law but no such theory has been accepted.
The images at the beginning of this section show the orbits of the various constituents of the Solar System on different scales. Some Solar System models attempt to convey the relative scales involved in the Solar System on human terms. Some are small in scale and may be mechanical—called orreries —whereas others extend across cities or regional areas. Distances are to scale, objects are not. Distances of selected bodies of the Solar System from the Sun. The left and right edges of each bar correspond to the perihelion and aphelion of the body, respectively, hence long bars denote high orbital eccentricity.
The radius of the Sun is 0. Formation and evolution Main article: As the region that would become the Solar System, known as the pre-solar nebula collapsed, conservation of angular momentum caused it to rotate faster. The centre, where most of the mass collected, became increasingly hotter than the surrounding disc.5 Surprising Facts About Over 50 Dating
Hundreds of protoplanets may have existed in the early Solar System, but they either merged or were destroyed, leaving the planets, dwarf planets, and leftover minor bodies. Due to their higher boiling points, only metals and silicates could exist in solid form in the warm inner Solar System close to the Sun, and these would eventually form the rocky planets of Mercury, Venus, Earth, and Mars. Because metallic elements only comprised a very small fraction of the solar nebula, the terrestrial planets could not grow very large.
The giant planets Jupiter, Saturn, Uranus, and Neptune formed further out, beyond the frost line, the point between the orbits of Mars and Jupiter where material is cool enough for volatile icy compounds to remain solid. The ices that formed these planets were more plentiful than the metals and silicates that formed the terrestrial inner planets, allowing them to grow massive enough to capture large atmospheres of hydrogen and helium, the lightest and most abundant elements.
Leftover debris that never became planets congregated in regions such as the asteroid beltKuiper beltand Oort cloud. The Nice model is an explanation for the creation of these regions and how the outer planets could have formed in different positions and migrated to their current orbits through various gravitational interactions. Within 50 million years, the pressure and density of hydrogen in the centre of the protostar became great enough for it to begin thermonuclear fusion.
At this point, the Sun became a main-sequence star.

This will mark the end of the Sun's main-sequence life. At this time, the core of the Sun will contract with hydrogen fusion occurring along a shell surrounding the inert helium, and the energy output will be much greater than at present.
The outer layers of the Sun will expand to roughly times its current diameter, and the Sun will become a red giant. Because of its vastly increased surface area, the surface of the Sun will be considerably cooler 2, K at its coolest than it is on the main sequence.
Eventually, the core will be hot enough for helium fusion; the Sun will burn helium for a fraction of the time it burned hydrogen in the core. The Sun is not massive enough to commence the fusion of heavier elements, and nuclear reactions in the core will dwindle. Its outer layers will move away into space, leaving a white dwarfan extraordinarily dense object, half the original mass of the Sun but only the size of Earth.
Sun Size comparison of the Sun and the planets The Sun is the Solar System's star and by far its most massive component. Its large massEarth masses which comprises Hotter main-sequence stars are more luminous.
The Sun's temperature is intermediate between that of the hottest stars and that of the coolest stars. The oldest stars contain few metals, whereas stars born later have more. This high metallicity is thought to have been crucial to the Sun's development of a planetary system because the planets form from the accretion of "metals".
Along with lightthe Sun radiates a continuous stream of charged particles a plasma known as the solar wind. This stream of particles spreads outwards at roughly 1. The interaction of this magnetic field and material with Earth's magnetic field funnels charged particles into Earth's upper atmosphere, where its interactions create aurorae seen near the magnetic poles.
The heliosphere and planetary magnetic fields for those planets that have them partially shield the Solar System from high-energy interstellar particles called cosmic rays.
