It's a lot of hard work, competing and not giving up. I think you get more appreciated the older you get.
I've never been one to be too careful with my diet. If I really start watching what I eat, I'm already a thin guy - I just won't have any physical strength. I think I'll disappear if I don't eat what I need to eat or what I like to eat.
Guys are bigger, stronger, just like in singles, serving bigger, returning better, and more athletic for sure. I think from my standpoint, just spending more time in the gym has enabled me to hang in there.
