Fit?: As you grow more fit your body will change how it sweats; it may be that you need to increase your level of activity as you've become too efficient to break a sweat at what you are doing now. There are rare cases where people are unable to sweat at all, but this is unlikely. If you are are really worried, see a dermatologist.
