You are looking really healthy lately . What are you doing differently ?   Thank you for noticing ! I've been making a few lifestyle changes over the past year .   Tell me about it . I'm interested .   Well , it all started when my brother challenged me to quit smoking .   Ha ! That's right . You used to smoke . I forgot !   When I kicked that habit , I found I had so much more energy . I started exercising .   At the gym ?   No . I like to be outside . I took up hiking and mountain biking .
