You can never have enough...

[R2x1]

I want a pedicure on script...

Those toes are getting further and further away.

Bloody hell - its not just me then! Damn things move further away every time.

Simple; we're growing old. Therefore, we're growing generally, not just old.
Growing taller, so socks and gardens are further away.
Growing stronger; remember what a struggle it was to carry home the shopping if mum had sent you down to the shops with 15/-7d to pay for it? (($1.58))  Now you can casually wander out of the butcher's shop carrying $150.99 of meat easily in one hand.
Stronger appetite.  Could you, as a 10 year old,visualise single-handedly eating a pie that cost well (or badly) over 2 Pounds? Then drinking three Pounds worth of coffee?
If you're concerned that weeding is tiring, consider that you're on one end of the weed, pulling. On the other end there's the entire earth!
Better memory. Honestly, can you recall your memory ever being better? That's not even making allowance for the fact that there's a lot more history to remember.
And if you're still concerned about getting older, consider that to the children of today, right now is going to be their good old days.
