I'm middle aged...

[OwlHoot]

I always thought:
0-20: youth
20-40: grown up
40-60: middle aged
60-65: (not sure)
65-80: senior citizen
80+: old age

Nah, it's:
60-75: wrinkly
75-90: crumbly
90+ : dusty

Mind you, I know several "dusties", including a couple of close relatives, who are as fit as butcher's dogs and fully compos mentis.

<100 = young
>100 = not so young

...and I'm only 35 ffs!!!

From the Beeb website about cancer deaths reducing in middle-age:

The number of middle-aged people dying of cancer in the UK is falling.
The analysis, which focused on people aged between 35 and 69, found the death rate fell by 2.4% each year over the last decade.

I would post a link but thats Milans job!!
