DR JOSE I agree also with what you are saying. Now of course everyone has to do everything....singers who dance and dancers who sing and dancers & singers who act....economics, I guess.
I can only say - as I have probably said before - I have danced since I was three years old....a very long time. I have studied all of the disciplines, most particularly tap and jazz (modern) - but also ballet....and certainly picked up swing and ball room along the way. My degree is in dance and Physical Education.

I love to dance. I have been doing it, teaching it, performing it.....I turned to choreography in my 30's, because that's just the facts of dancing life. Sure I still perform, sure I still do a part now and then, sure I still keep up with what's happening.....am I in shape? No. And it's terrible. Being in the studio regularly and seeing yourself in those full length mirrors 8 hours a day keeps you very body conscious.
Now at age 59, I have probably danced my last show....and maybe even choreographed it.....but when some really good music plays....I can't stay in my seat. I can still partner.....and heck....maybe I WILL see if I can choreograph a show this year....I have ideas for HELLO DOLLY! that I haven't used!
