GEESH! Even getting too old for the beach!

Went today, got out there about 9:45. Packed three waters, 4 Bud Lites, sandwich and chips. I was out there for only 4 and a half hours and I feel WHOOPED!!! 25 years ago, I could go out there for EIGHT hours, put down 12-15 Bud Lites, play football, body surf for a couple of hours, come home, shower and then go hang out with my buds till Midnight. NOW??? My eyes are burning. I'm hungry and thinking about bed time already! LOL
