[header] How to exercise to prevent blood clots [title] Get up and move around. [step] Whether you're traveling by train, plane, or automobile, long-distance travel involves a lot of sitting. When you sit, you decrease circulation in your legs-especially if you sit with your legs crossed or with one foot under you. <sep> (A) If you are on a train or coach, the seat underneath you always feels flat, as if you are sitting. While there are good ways to stretch out your legs, there is not a lot a group of people can do. (B) This will help promote blood circulation to your feet. It will also keep you from rubbing your legs in an annoying manner-you can't promote blood flow when you're sitting on one leg. (C) [substeps] You can exercise while you drive or driving, although getting up and down on the exercise train can significantly improve circulation. You can also listen to music while you exercise, which will also help to prevent blood clots. (D) [substeps] If you're on a plane, try to get an aisle seat so you can get up and move around more easily. Ideally, you want to get up and stretch your legs or walk up and down the aisle once every hour or so.

[header] How to come out as transgender [title] Know your audience. [step] Think about the people in your lives, and that ones who you trust. You may have certain friends or relatives who are more understanding and loving than others. <sep> (A) If you know very few other people that you trust, you won't have to worry about identifying a transgender family member if you feel like everyone in your family can identify transgender. [substeps] In the u.s., you only need 3 or 4 transgender relatives, and 5 or more friends or relations. (B) Write about that with them to solidify that you are transgender. You may also consider joining a church or non-denominational campaign to bring out your transgender identity. (C) Evaluate both the people who will likely support you and those who may not. [substeps] If you are a minor, the coming out process may be more challenging since your parents are still legally responsible for you. (D) Maybe they are-and don't realize it. You can't change them if they aren't accepting of you (unless you reach out a close friendship with them and they become impatient or show empathy), but you can help them be more open about their conversation with you.
