At first glance, the inclusion of the term ?fingers? in your question
may cause a commenter to ponder its relevance, as it is true that the
distribution of the two types of sweat glands differ throughout the
body (Eccrine: over all of the body, particularly on the palms of the
hand, soles of the feet and forehead; Apocrine: mostly confined to
armpits and genital/anus area). However it is safe to exclude the term
(hence the answer as given) as the basic percentage remaining the same
(approximately), with some small variances caused by situations such
as the prevailing health of the individual concerned, or an individual
experiencing a major change in ambient temperatures (eg. moving to a
hot climate is likely to produce in the short term a higher amount of
sweat with increased salt content, however water content remains in
the 98%+ range) etc.
