In recent years he's starting to really age. His neck is curving a bit (the actual neck is getting shorter/hunched look). His legs look strange these days and in general he seems to have lost some height and muscle tone. Not surprising for a man approaching 67 years old.
What a complete and utter prick to write such shit about Lemmy.
I hope the writer of this post is in half as good shape as Lemmy when he/she is 67. I know I won't be.
