Article: Since your fingernails are the canvas for your nail art, you want to start with a healthy surface. Strong nails will allow your nail art to look great and last for a long time. To improve your  nail health, start with your diet. Make sure you are getting enough biotin, Vitamin E, and omega 3s. If you need help getting these nutrients, try taking a supplement. Protein rich foods will also help your nails grow, so be sure to eat beans, fish and nuts. Additionally, keeping your hands and nails moisturized and protecting them from harmful elements, such as harsh weather or cleaning chemicals, will go a long way. This will allow the polish to adhere to your nails. It is important to remove any lotion, dust, or water on your nails right before you begin. These elements create a slick surface that hinders the nail art from adhering and will lessen the nail art's longevity. Starting with a clean surface also helps nail polish to dry quicker and prevents smudging. To fully remove any oils that might be on your nails, try using nail polish remover before you start, even if you're not wearing nail polish. Apply any kind of nail polish remover to a cotton round and brush over each nail to start with a clean surface. Avoid ingredients like formaldehyde, toluene, and dibutyl phthalate (DBP), which raise health concerns and have been shows to be allergens. Also, try not to use quick drying nail polish, which can dry out your nails, or hardening nail polish, which can result in your nails breaking or cracking. Instead find nail polishes that are labeled “three-free” to show that they do not include harmful ingredients. This will allow you to wear your nail polish for an extended period of time without it adversely affecting your health. Besides protecting your nails from stains, a good base coat gives the polish an ideal surface to adhere to. It creates a sticky surface that the polish will grab onto so that it lasts longer. A good base coat also creates an even surface for your nail art and certain formulas can moisturize your nails. Just make sure to use a quality base coat or it can end up doing more harm than good.  Give your nails two thin coats of base. It acts as double-sided tape for the polish and creates a barrier between your nail and the polish. Never use top coat as base coat. Top coat is much thicker and has different chemical properties than base coat. It also dries much slower and doesn't have the sticky power of base coat. Not all clear nail polishes are created equally!

Problem: Article: All music has a beat or basic rhythm to it that can be counted. Music has a certain number of beats per measure, which is usually 3,4 or 6 beats. In salsa music there are 4 beats per measure. The basic salsa dance step uses 2 measures of music, or 8 beats.  Try clapping the rhythm of the music while counting 1-8. Beginners should use salsa music that has a slower beat and an accented percussion. This will help you hear the beat in the music. Some good starter songs are "Slow Salsa" by Jimmy Bosch, "Cuera Maraca y Bongo" by Los Nemus, "Cosas Nativas" by Frankie Ruiz, or "Yamulemau" by Richie Ray and Bobby Cruz. The basic salsa step uses 8 beats to complete, however you don’t step on all 8 beats. Your feet move on beats 1,2,3 with a pause on beat 4; you step again on beats 5,6,7 and pause on beat 8.  Clap when you will be stepping, and don’t clap when you don’t step to understand the rhythm of the dance step. The rhythm will be clap-clap-clap-pause-clap-clap-clap-pause. Repeat this rhythm throughout an entire song. Try standing and marching your feet in place using the salsa rhythm you just clapped. Step your feet down on beats 1, 2, and 3, pausing on beat 4, and repeat the sequence for beats 5 through 8.
Summary: Listen to music to hear the beat. Clap the rhythm of the steps. March the rhythm of the steps.

Depending on what you were doing with your hands before you remove your mask, you may need to wash your hands.  Or you may need to remove medical gloves, wash your hands, then remove the mask. In general, remove the mask by only touching the edges, straps, loops, ties or bands.  Do not touch the front portion of the mask which may be contaminated.   Ear Loops — Use your hands to hold the ear loops and remove them from around each ear.  Ties/Straps — Use your hands to untie the bottom straps first, then untie the top straps.  Remove the mask while holding onto the top ties.  Bands — Use your hands to bring the bottom elastic band up and over your head, then use your hands to do the same with the top elastic band.  Remove the mask from your face while holding the top elastic band. Medical masks are designed to only be used once.  Therefore when you take the mask off, place it in the trash immediately.  In medical settings there is most likely a garbage bin specifically for biohazardous items like used masks and gloves. In a non-medical setting where the mask could be contaminated, place the mask by itself inside a plastic bag.  Tie the plastic bag closed and then throw the plastic bag in the garbage bin. Once you’ve disposed of the mask safely, wash your hands once more to ensure they’re clean and didn’t get contaminated by touching the dirty mask.
