[Q]: [header] How to turn forty gracefully [title] Set a realistic weight goal. [step] A realistic weight goal should be based on the body and limits of your current self, not the self you wish you had or the self you had twenty years ago. Your goal should be specific and measurable, and limited in time. <sep> (A) [substeps] For example, if you are 35 years of age and have an empty stomach, then set a goal to lose ten pounds in thirty years from now on. Keep in mind that you will not see the difference in yourself if you start getting older. (B) If you are unable to accomplish a current weight goal, you should also consider setting another goal, often known as a baptism goal. Baptism goals provide an answer to both your doubting thoughts and worried questions. (C) [substeps] For instance, a goal to lose twenty pounds is a good goal. A goal that is vague like " i want to get fit " is not measurable. (D) [substeps] For example, if you are looking to reduce your overall physical limits, you might set realistic weight goals. For example, you might set out to lose 30 pounds in one year and then lose 20 pounds in another year, and then lose 25 pounds within that year.

[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.
