( CNN ) -- You can tell a lot about a person by the T-shirts they wear . Each T-shirt has a story to tell -- a story that , in some cases , can span decades . Where did they go to college ? What sports did they play in high school ? Do they run 5Ks or marathons ? I , myself , have a favorite T-shirt -- size medium . It 's navy blue , and I received it for attending a baseball camp when I was 11 . Attending that camp was one of the highlights of my youth . I wore that T-shirt more than I should have . In high school , I would wear it underneath my soccer and baseball jerseys . In college , it served as my personal pick-up basketball uniform . I still have that T-shirt . Today , it 's resting safely in a drawer at home . The sleeves are missing , and it 's a tad tight , but I still have the tee and everything it represents . To me , it stands for countless hours of hard work and sweat . It stands for my love of sports that was second to none . What would I find if I were to go through your stack of T-shirts ? What T-shirts would you be proud of ? Which ones would define you ? Getting fit for the family I love . As you know , my goal is to complete the Nautica Malibu Triathlon in September with my fellow Fit Nation teammates . At the end of the race we will undoubtedly be handed an official race T-shirt . ( Last year 's T-shirt was black and looked really cool . ) Now , I 'm not implying that I am running the race solely to inherit another T-shirt , but it will surely be a great reminder of the experience . Needless to say , the T-shirt will be one that I cherish . When I die , I want the people packing up my belongings to find my collection of old T-shirts . Hopefully , after sifting through the stacks , they 'll find my 2013 Malibu triathlon shirt and wonder , `` How did he get this ? Did he really run a triathlon ? '' If only they knew . If only they knew about the hard work that went into earning that T-shirt . That T-shirt will have a story to tell , too . One that began on a cold day in January 2013 , and hopefully , one that will never end . Do you have a favorite T-shirt you 'll never give away ?
