Not sure about your age but remember you spend a lot of your time and energy at work and sometimes we get burnt out/bored even doing what we know well.
Despite a great crew to work with , would you really be happy with yourself?
The $ don't help.
Would you bash old ladies if the money was good?
From your comments , no.
Make the change and get out while you can.
Those opportunities don't always come along.
Just my 2 yen worth :)
