[Q]: [header] How to stay beautiful [title] Adhere to a proper diet. [step] Most people think of dieting as cutting back on food, or at least eating less of the things you want. Fortunately, this is not the case. <sep> (A) Even though eating less is important, some people find that excessive calories will trigger body type issues like a body mass index, which is the fact that people aren't too quick to begin with a meal. [substeps] Inadequate sources of protein (such as meat or peas) are also linked to body image issues like muscle loss. (B) Instead, a proper and sustainable diet replaces empty calories (like processed cheeseburgers and soda) with healthy alternatives. Depending on what your diet currently consists of, you can probably think of at least a few things you eat that your body would technically be better off without. (C) You simply remember your body and the things you need to eat to stay healthy. Get enough calories and get into shape. (D) There is a tendency of people to end up missing out on calories because they're trying to stay healthy. In fact, it can be hard to keep up with it because you simply try to make yourself feel better.

[Q]: [header] How to paint masonry walls [title] Remove any flaked or peeling paint from the masonry. [step] If the wall has already been painted, you need to remove any old paint that is loose, peeling, or flaking away. On an exterior wall, this is most efficiently done with a sandblaster. <sep> (A) New paint must be removed from the wall first, gently scraping around the edges with a rat-tail tail reciprocating scraper. This is most often done on exterior paint walls that are still meant to protect it from debris. (B) In areas where a sandblaster would be too messy and cumbersome, loose paint can be removed with a stiff wire brush and a paint scraper. [substeps] Failing to remove loose and peeling paint can result in the paint flakes mixing in with your fresh coat of paint and marring the finish. (C) [substeps] Make sure to turn off the water. Do not flush the wall down the drain. (D) If there is a paint-resistant paint strip still clinging to the wall, it may be painted to the wall as well, but not directly under it. [substeps] Using a sandblaster may be wise, but if the paint is not taking off, it may be better to start by sanding lightly.

[Q]: [header] How to clean a seat belt [title] Pull out the seat belt. [step] Vigorously pull the belt forward until it is stiff and doesn't move anymore. When this happens, the entire belt will be unspooled and much easier to reach. <sep> (A) [title] Run a plastic scraper along the inside of the belt. [step] It's better to be careful than to damage the plastic. (B) If you are comfortable keeping your legs apart, pull out the seat belt and give it a good scrubbing with a hose set to medium. Using a nylon pull belt should provide you with some success for that purpose. (C) [substeps] Note that you should only pull out the seat belt if your manual safety toggles off. [title] Apply vinyl seat wax to the belt. (D) [title] Place a clamp near the belt reel. [step] Follow the belt strap upwards and locate the reel.
