Stiffen up.

My feets have been threatening to break through some boards out the back lately so Jimmy replaced a couple of them. It's only a little job but these things are becoming more difficult for me now.
The last piccie is of a wafer thin bit of an old board.
In my younger days I would have been half a packet of nails trying to bash them through the solid new board, but now that I have a fair variety of tools I made life easier by drilling pilot holes.
