You can expect to see students bailing from Math 55 on a regular basis. The class size shrinks to half its original size or less before the semester is over. According to one student who took Math 55 in 2005, and kept a running tally of attendance, "We had 51 students the first day, 31 students the second day, 24 for the next four days, 23 for two more weeks, and then 21 for the rest of the first semester after the fifth Monday

As author Sam Williams describes in Free as in Freedom, his biography of free-software pioneer (and Math 55 graduate) Richard Stallman, the course is "four years' worth of math in two semesters."

According to a freshman guide to Harvard's Mathematics Department, there are two first-year math courses, the hardest one being Math 55. You could take Math 21, which is taught by graduate students and where homework usually takes a reasonable three to six hours per week. Or, you could opt to take Math 55—which gives you 10 times the amount of homework.

One former Harvard student, a self-described "Math 55 groupie," told The Harvard Crimson, "These guys are my role models." And a 55er (that's what Math 55 students call themselves) could confirm: When people find out, they "just spontaneously combust, swoon, faint, turn bright red, start giggling."

To get a sense of the kind of brains it takes to get through Math 55, consider that Bill Gates himself was a student in the course. (He passed.) And if you'd like to sharpen your brain like Microsoft's co-founder, here are The 5 Books Bill Gates Says You Should Read.

Like lipstick, your eye makeup can make you look older if you choose the wrong shade(s). Smoky eyes, for instance, are chic, but they can also have an aging effect. "Using color cosmetics that are either dark or very bold can accentuate lines," says Brice. "If you can live without expressing yourself through bold or bright colors, it may help you look younger." She also notes that glitter eyeshadows can similarly emphasize lines

While using the right foundation is key, what goes with it is equally important—and we're firm believers that a touch of lipstick can fix everything. However, as you get older, you'll want to consider an exact hue. "It's important to not only look at how it interacts with your skin tone but also with the color of your teeth," says professional makeup artist Mandie Brice. "Certain shades that are yellow- or red-based without any blue or purple tint can make teeth look more yellow, which is a sign of aging."

We've all heard the phrase less is more. Turns out, that applies to makeup, too. "One of the most common makeup mistakes that makes people look older is using too much foundation," says Laura Roncagli, a professional makeup artist and co-founder of MyBeautik.com. "Foundation can make your skin look cakey and can settle into wrinkles, making them more obvious."

The top aging makeup mistake doesn't have anything to do with makeup at all. Instead, it has to do with your base. "When makeup rests on dry skin and facial features, the skin absorbs it as though it is a skincare product," says professional makeup artist Mary Winkenwerder. This "produces uneven color and does not present a healthy statement."

Let's face it: Putting on makeup is one of the best parts of the day. Not only is it a soothing self-care experience, but it also allows you to play up your features and express your creativity. But beware, whether you're in your twenties or are enjoying retirement, the wrong makeup techniques can actually make you look older.

Besides staying on top of your harvesting duties, other simple tasks can help cut back on attracting mice or rats to your yard. Bagging and removing all untidy piles of dead plants, clippings, brush, and gardening materials such as unused pots or soil bags will give rodents fewer places to take shelter. Experts say this also involves keeping any grass in your garden trimmed, moving any nearby woodpiles where mice can take up residence, and making sure to rake or remove any fallen foliage regularly.
