Way to go! Great work.
It's a bit scary how similar your situation is to mine. Actually, I was even planning on posting a message when I reach 70 (I've been stuck at 67.5 for a while now btw, haha)
Like you, I've recently fallen in love with weightlifting and sometimes wish I had started about 15 years sooner.
You just can't beat the value of good coaching and the camaraderie among your fellow lifters.
