Some things really change with time.

They say as you get older you can't do the things you used to. Like going for days without a lot of sleep. I remember when we used to stay up until the sun came up...catch a couple hours and do it all over again. Staying up until the sun comes up now means I will need to sleep until the sun goes down. I've learned sleep is important and a wonderful thing in life. Although every now and then there are some things worth missing a little sleep for.
