In one sentence, describe what the following article is about: Using a clean, lint-free rag or a washed finger, gently rub inside the case wells to dislodge any biofilm that may be stuck to the plastic. To achieve maximum cleanliness, try to cover all interior surfaces of the case and spend at least five seconds rubbing each area. Get out your bottle of multi-purpose contact solution and gently spray into the open case. Continue until you are satisfied that any debris have been removed. Don’t forget to spray solution onto the underside of the lids as well.  Spraying is a critical step in bacteria prevention. One study reported that 70% of contact cases contained bacteria and other contaminants.  Make sure to use the multi-purpose solution that your doctor suggested. Using a standard saline solution or wetting solution will not sanitize your case properly. As a general rule, you want to keep your contacts and your contact case away from all types of water. Do not rinse your case out with water. Doing so could potentially expose you to Acanthamoeba keratitis, an eye infection that can lead to blindness. After you’ve completed the rinsing process, set out a clean tissue or a clean lint-free cloth. Place the case and lid caps on the tissue. Place them either facing up or down, depending on your preference. Some argue that face down is better as it protects the case from airborne contaminants, like those commonly found in a bathroom. When your case is completely dry, you can then refill it with fresh contact solution. It is ready to store your contacts at this point. Consider carefully where you place your contact case during all phases of use. Cases are more likely to be exposed to bacteria in humid environments. Leaving your case in a bathroom, and near a toilet in particular, may cause it to come into contact with contaminated water droplets. You may want to consider a nightstand as an alternative storage option.
Summary: Scrub the inside of the case. Rinse out the case with a lens solution. Avoid exposing your case to any water. Let your case air dry. Refill your case with solution. Store your case in an appropriate area.

In one sentence, describe what the following article is about: One key part of fat loss is exercise.  Cardiovascular (cardio) or aerobic exercise helps your body burn calories and can support your weight loss.  Maintaining the body’s lean muscle mass and burning calories can be accomplished by performing cardio exercise regularly. Aim for about 150 minutes of cardio each week. Ideally, the exercise performed should be at moderate intensity. This is any activity that raises your heart rate and breathing to a level where it's still comfortable for you to say short sentences without stopping for a breath.  Different types of aerobic activity can include: walking/running, biking, using the elliptical, swimming or dancing. Interval training is a combination of strength training and cardio in short bursts of high and moderate intensity exercises. You can do these types of activity for shorter amounts of time.  Studies show that this type of activity helps support fat loss. A crucial part to fat loss and muscle mass maintenance is strength training. Consistent weight training helps prevent muscle mass loss and can increase the amount of lean muscle mass.  Strength training should be done for about 20–30 minutes per session. Try to work every major muscle group during each training. Make sure to work: core (back, abs and glutes), chest, arms and legs. Strength training activities include: weight lifting, isometric exercises and classes like yoga or pilates. If you're just starting out with weights or strength training, start with low weights and a few repetitions. Do not start out with overly heavy weights or train for long periods of time - this could cause injury. Limit your training frequency for each muscle group to every other day at a maximum. Each specific muscle group should only be directly stimulated one to two times per week in order to allow for full recovery time. Taking a day or two off within the week will help your body recover and continue to maintain and build lean muscle mass. It's important to take off between both cardio and strength training throughout the week.  Allow for about 24–48 hours of time off between strength training sessions.  When you take a "rest day" you should still be active. Rest days should not include a lot of sitting or laying down. You should perform very light intensity activity and restorative activity.  You can do: walking, a leisurely bike ride, or restorative yoga. When you're dieting, working out and aiming to maintain or build muscle mass, it's important to focus on proper nutrition immediately before and after a workout.  Prior to a workout, it's ideal to consume a lot of hydrating fluids and also a small carbohydrate-rich meal. This should be eaten at least 30 minutes prior to your workout to make sure you don't have any GI upset during your exercise program. Pre-work out snacks include: small bowl of oatmeal, small piece of fruit, individual yogurt or a serving of whole wheat crackers. Immediately after a workout, it's also important to continue drinking hydrating fluids. In addition, you should consume a small meal or snack that contains protein and carbohydrate.  This combination in particular helps muscles recover. Try to eat within 60 minutes of completing your workout. Post-work out snacks include: hummus and whole grain pita chips, small apple and peanut butter, chocolate milk, trail mix with dried fruit and nuts, or a fruit smoothie with added protein powder.
Summary: Do cardio exercise three to five times per week. Perform weight training two to three times per week. Include enough rest days. Focus on proper fueling and recovery.

In one sentence, describe what the following article is about: If there is visible mould, or a rancid odour, the avocado is not safe to eat and should be discarded. If the avocado is severely dented and marked, or has squashed areas it has likely gone bad. Different varieties of avocado have different skin colours. The most common variety of avocado, the Hass, will change colour to very dark green or purple colour when ripe.   If a Hass avocado has reached a deep black colour, it may be past its prime. Most other commercially available avocados, like the Bacon, Fuerte, Gwen, Pinkerton, Reed and Zutano retain a green colour even when ripe. Take care not to bruise the fruit with your fingertips. A ripe avocado will yield slightly with light force. If slight pressure leaves an indent in the avocado, it is a sign it has gone bad. Some people advocate checking for softness by pushing in or removing the stem. If the stem moves easily it means the avocado is ripe. Once the stem is removed the colour of the flesh is also revealed.  This method may be effective when judging softness but not when judging colour. To get a good indication of the quality of the flesh more surface area needs to be seen. If you are examining avocados to purchase, you should avoid tampering with the fruit in this way. Removing the stem can compromise the quality of the fruit for other prospective purchasers. If you already own the avocado, this is the quickest way to determine if it has gone bad. The flesh should be a light green colour. If the flesh is black or brown, the avocado should not be eaten. If there is some minor bruising in the form of small, isolated areas of brown discolouration, the avocado is okay to eat. If you have thoroughly inspected the flesh but are not sure whether the avocado has gone bad, it is safe to perform a taste test. Avoiding any brown spots, try a small amount of the green flesh. Avocado should be creamy, mild and subtly sweet. If it smells or tastes musky or off, it has gone bad.
Summary:
Look at the outer skin of the avocado. Check the color. Hold the avocado in your hand and apply gentle pressure. Using the stem of the avocado to check for ripeness. Cut the avocado open. Taste the avocado.
