My husband used to say that about reaching 40 cause he is an alcoholic. But... at 39 got sick, died twice in ICU & when finally came off ventilator, he woke up preaching like he was at the pulpit that he'd never drink again & he never has, we are 54 now. Oh, he got sick as a direct result of 22 years of hard drinking. He does still have to take meds. though.
So... now he's glad he had a wake up call cause he's still glad to be alive.
