I'm age 41.
Feel your age- No I feel I have a young, youthful attitude and have not forgot how to laugh at daft things.
Look your age- I like to think I look younger(Good diet and exercise over many years have paid off) A sexy barmaid at a place I was DJing last night thought I was alot younger when she asked my age

(Nee Pic's,soss)
Act age- As and when required, but fuck that, lifes to short to be a serious head numbnut who has forgot the Joys of youth and considers most of it as immature.
