Daryl Dragon (The Captain) is 71. Yeah, it's Dragon.
Daryl tells TMZ ... "I don't know why she filed. I gotta figure it out for myself first." He also said they're still living together in the same house.
According to the divorce docs, obtained by TMZ, there's special mention about health insurance coverage, and that seems relevant, because in 2009 Toni blogged that Daryl had been diagnosed with Parkinson's.

The blog has an update on Jan 16, 2014, saying "The Captain & Tennille appeared to the public as them being the ideal model for a 'rock-solid' married pair. But almost all people naturally evolve over time, & sometimes hidden feelings start to be uncovered ..."
