Newly 60 and wanting to love it!

July 4th I turned 60 and have promised myself that by 61 to be healthier and in the best shape ever. At the urging of my sister I joined MFP tonight. I've been reading all through the Message Boards and love the friendliness and help that everyone is so willing to give. My problem is I feel like I have no metabolism at work.... how can I rev it up? Would love some new friends!
