PROBLEM: [header] How to choose the best hula hoop (adult sized ) [title] Measure your height from the floor to your belly button. [step] This measurement will then help to determine the diameter of the hoop you should purchase. The hula hoop, when resting vertically on the ground, should reach somewhere between your waist and mid-chest. <sep> (A) [substeps] Example: if your height is 36 inches (76 "), then 118 inches (77 ") would be the minimum height. For kids, this would be 24 inches (76 "). (B) This is your base diameter measurement and can be adjusted slightly depending on your size and experience level. [substeps] For example, most adults will begin with a hula hoop between 40 and 44 inches in diameter. (C) [title] Find a hoop that you know you can balance on. [step] This will improve the stability of the hoop and prevent you from accidentally dropping the ball while on it. (D) Your waist should be about an eighth of an inch shorter than the hoop. You should also measure your waist from hips to ankles, and to knees with a ruler or measuring tape.

PROBLEM: [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.

SOLUTION: B

PROBLEM: [header] How to deal with a boyfriend who wants more space [title] React in a calm way. [step] People often fall into the trap of thinking that time apart is a bad thing in a relationship. While excessive time apart can point to problems, a little bit of space from each other is normal and necessary for a healthy relationship. <sep> (A) Many people fall into the trap and have ended up feeling a silly sense of happiness for long periods of time. [substeps] Let your husband or girlfriend know that you can't be apart for the next month so talking about the situation will help him or her get used to this new change as well. (B) It gives both partners time to do their own thing, and allows you to have more things to talk about. [substeps] Avoid harassing your partner by saying things like " so, you have something better to do than spend time with me? " [title] Clarify the situation. (C) People that force distance to hurt is often the opposite of human nature; therefore, when feeling put off or untreated, space might be necessary. [substeps] Try to have a respectful attitude towards each other and make this time count. (D) For example, you don't need time away from him every day; a single night spent staring into your laptop screen or phone phone screen might be all he needs right now. However, this doesn't mean you should no longer be together, of course.
