Surf clubs will be happy to chat to you and tell you what is required if you want to be a volunteer lifeguard. <sep> (A) [title] Find the best and safest surf-life saving club in your area. [substeps] Surf lifeguards live off the beach, and they will probably need two-way water transportation, quite possibly a car or bicycle. (B) Many will provide all the training you'll need. Call them, check out their websites or simply head down and chat to them. (C) This can be achieved by attending the lifesaving club on the first day, then going on to other lifeguard's clubs along the way.

They will be able to suggest hours of work that are perfect for you or your specific lifeguard job.

Example Input: [header] How to dry out wet currency [title] Find a dry space. [step] Make sure the bills are kept in a room with good air circulation to lessen the time it takes for the bills to dry. Keep the bills in an area where they won't get blown away or easily lost. <sep> (A) [substeps] At home, you will be able to air dry your currency if your bills stay wet. [title] Store your currencies in a dark, dry place. (B) Avoid putting the bills near open air vents or next to tight crevices where the bills could fall. Try arranging them on the edge of a sink so the water will drip to the ground. (C) Good air circulation should not damage the bills, but it shouldn't be expensive either. [title] Make sure the area is clear of wet or air-logged fabric or paper. (D) [title] Keep your bank account secure if possible. [step] Also, to help the currency from drying out, make sure the extra cash is well hidden in the bank so it isn't moved quickly to prevent the contents from spoiling or breaking up in transit.

Example Input: [header] How to live a fuller life after middle age [title] Decide what's most important to you. [step] Now that you've passed middle age, you really don't need to be wasting time on things you don't enjoy. That means you need to figure out what you do enjoy spending your time on. <sep> (A) If you're not devoting more time to it, you're really off on the right foot. You also don't need to spend all of your time thinking about stuff you really want to accomplish (like finding a job or fulfilling your own little dream). (B) Maybe you love throwing yourself into your work, or maybe your home life is more where you're focused. Maybe you love to travel and have adventures. (C) Being married or having children is perhaps the most important thing to you about yourself in general. Consider what activities and talents you enjoy most-such as traveling, playing an instrument, and controlling certain things. (D) [substeps] It's all about the things that matter to you personally. What you enjoy, what you don't, or what bothers you the most are the factors that make you want to focus all your time on yourself.
