Old guy pop-up

This is an interesting post from silversurferdude.com. I often do this when tired at the end of a session and expect to do it more often as I move into my 70's.

I have pretty much given up to do a proper pop up. Now I first get to my knees. But i am surfing, and catching a lot of waves.
If you are an older person like me ( 64 years ) you can try doing the pop up more slowly using your knees.
I am experimenting with surfing the first part of the wave as a kneesurfer. As soon that I feel that I have the wave, I get to my knees. Lean to one side. You turn in that direction. If the wave looks as if it is just about to break, then I go straight down and lean back to keep the board from pearling. Or hold in one rail ( rail grab ) to get a sharp turn You then have more time to look around at the line up, if somebody are trying to take off from the same wave. Also you avoid a lot of nasty falls.
I believe older people simply have not got the fast reactions and the flexibility, as you find in a young person. Your surf style must therefore follow different rules
