Love both for different reasons - only recently started standard though and want to continue doing both for now. I suspect my latin is not that great but currently not too fussed and willing to work on it.
On subject of 'older people' doing latin - recently went to a pro-am show where 90% of the students were over 50. Majority did standard but those that did latin looked fab, great dancing & technique (I doubt very much I would've achieved the standard they were at) and the 60+ lady that asked my DP to jive really went for it - DP exhausted. Was the end of dancing for that evening!!! So think age shouldn't stop one doing latin and am currently encouraging my mother
