I'm sad to hear this news too. I did like their songs and show.

The way I look at it is ages wise is,
1/3 of life is up to 25
2/3 is 25-50
Last 3 is 50-70
Anything after 70 is Bonus years. All this talk of a lot of us living to 100 is in my opinion nonsense, take a walk around any cemetery and its surprising how many go around the 70 mark.

Middle age is approx 40-60
Old or senior age starts at 60-65 (though I read once that scientists said that if they had to define an age that old age starts at they would pick 50!) I guess that would put me at the start of old age then.
