Senor Jeff, happy 40 you old man you and welcome to the club!
This is where I would go on and on (and on) about all the things that suddenly started hurting and stopped working after I hit the 4 decade mark. This is not to mention the things that bounce (that shouldn’t) when I walk fast. However, some fool told me that 40 is the new 30 and I am pretending that this is true.
I highly recommend that you join me in believing this complete line of BS, that way we both have 10 more years to start complaining about all those things.
Cheers my friend!
