Happy Birthday, Emoticons :-)

There are certain things so ubiquitous—things we all have used and enjoyed like we share equal ownership over them—that it is hard to imagine any single mortal person creating them. Things like this:
 
But the emoticon, that display of feeling crafted from punctuation, does have a birth story, and it unfolded exactly 32 years ago today, on Sept. 19, 1982.
 
Scott Fahlman, a computer scientist at Carnegie Mellon, noticed that conversations were going awry on electronic message boards the staff was using to communicate in the early 1980s. Jokes were being lost, tones were being misconstrued and unnecessary tirades were eclipsing the intended discussions. So Fahlman, then in his early 30s, made a simple, legendary suggestion: if you’re being humorous or ironic, label your comment with a smiley face made of a colon, dash and parenthesis.
 
Soon emoticons were spreading to other universities, then seeping into emails and eventually text messages across the world, filling the giant hole left by all the visual cues present only in face-to-face communication. The tone of one’s voice, the furrowing of one’s brow, the erect middle finger. “One of the main problems with text communication is that it’s just different from how we’ve talked to each other for most of the existence of language,” says computational linguist Tyler Schnoebelen, who wrote his thesis on emoticons at Stanford. “There they are, these words, sort of flat. We’re depleted, we’re dry in terms of the cues we get to use to signal exactly what we mean.”
 
And that is where emoticons have come in so terribly handy. The twist is that 32 years into this wild ride, emoticons are giving way to more colorful, more elaborate Japanese-born cousins: emoji. Those little images—invented in the ’90s by telecommunications planner Shigetaka Kurita—are much more versatile than punctuation will ever be. They’re easier to use and more efficient; three clicks can give you all this
 
From Facebook's Finch collection of emoji, which the company calls "stickers."
 
But on this momentous occasion of the emoticon entering its 33rd year, let us take a moment to appreciate the qualities it has that emoji do not. For one, developers and designers are flooding our operating systems with their own versions of emoji (like Facebook’s) — which, unlike uniform colons and dashes, are all different. Though most people are familiar with the emoji Apple designed (like those in the above paragraph), there is no standard set. So some only work on this browser or that phone and often what we get, instead of that important, clear visual cue of a person’s meaning, is this unhelpful thing signifying that an icon should be there, but is not:
 
In an attempt to one up each other, emoji developers have also started making symbols that can actually confuse situations as much as clarify them. Take this adorable yet semantically unhelpful emoji from social app Line:
 
You know, for those times when you’re expressing something that really won’t come across quite right without a half-peeled banana with a milk mustache.
 
It is, of course, lovely that texters have the option to add this to their epistle, but there is a simplicity it lacks that an old-fashioned, primitive emoticon like ; ) does not.
 
Emoji are indisputably the cool kids to the emoticon’s awkward yet lovable science teacher. But they’re not dead yet! Until there is a standardized set of emoji—or software capable of translating all images onto all electronic devices as senders intended them—people will be relying on these 32-year-old standbys. So happy birthday to you, you little symbolic gems, and thank you for all your fine work so far = ).

Exercise: 7 benefits of regular physical activity
 
You know exercise is good for you, but do you know how good? From boosting your mood to improving your sex life, find out how exercise can improve your life.
By Mayo Clinic Staff
 
Want to feel better, have more energy and even add years to your life? Just exercise.
 
The health benefits of regular exercise and physical activity are hard to ignore. Everyone benefits from exercise, regardless of age, sex or physical ability.
 
Need more convincing to get moving? Check out these seven ways exercise can lead to a happier, healthier you.
1. Exercise controls weight
 
Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn.
 
Regular trips to the gym are great, but don't worry if you can't find a large chunk of time to exercise every day. Any amount of activity is better than none at all. To reap the benefits of exercise, just get more active throughout your day — take the stairs instead of the elevator or rev up your household chores. Consistency is key.
2. Exercise combats health conditions and diseases
 
Worried about heart disease? Hoping to prevent high blood pressure? No matter what your current weight is, being active boosts high-density lipoprotein (HDL) cholesterol, the "good" cholesterol, and it decreases unhealthy triglycerides. This one-two punch keeps your blood flowing smoothly, which decreases your risk of cardiovascular diseases.
 
Regular exercise helps prevent or manage many health problems and concerns, including:
 
    Stroke
    Metabolic syndrome
    High blood pressure
    Type 2 diabetes
    Depression
    Anxiety
    Many types of cancer
    Arthritis
    Falls
 
It can also help improve cognitive function and helps lower the risk of death from all causes.
3. Exercise improves mood
 
Need an emotional lift? Or need to blow off some steam after a stressful day? A gym session or brisk walk can help. Physical activity stimulates various brain chemicals that may leave you feeling happier, more relaxed and less anxious.
 
You may also feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem.
4. Exercise boosts energy
 
Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance.
 
Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.
5. Exercise promotes better sleep
 
Struggling to snooze? Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep. Just don't exercise too close to bedtime, or you may be too energized to go to sleep.
6. Exercise puts the spark back into your sex life
 
Do you feel too tired or too out of shape to enjoy physical intimacy? Regular physical activity can improve energy levels and increase your confidence about your physical appearance, which may boost your sex life.
 
But there's even more to it than that. Regular physical activity may enhance arousal for women. And men who exercise regularly are less likely to have problems with erectile dysfunction than are men who don't exercise.
7. Exercise can be fun … and social!
 
Exercise and physical activity can be enjoyable. They give you a chance to unwind, enjoy the outdoors or simply engage in activities that make you happy. Physical activity can also help you connect with family or friends in a fun social setting.
 
So take a dance class, hit the hiking trails or join a soccer team. Find a physical activity you enjoy, and just do it. Bored? Try something new, or do something with friends or family.
