Erm no. If its what they enjoy then
Obviously if it stops being safe for them to drink then its slightly different, but even then, still their choice. I know I wouldn't give up my vices once I hit a certain age just because they are deemed more dangerous for whatever reason
My mother in law has actually just given up drinking entirely, not touched a drop in 5 months now. From being a raving alcoholic for like 40 years. Just quit overnight. Because shes been put 'on tablets' and has convinced herself that its really really dangerous and many die from drinking when on meds. Obviously its not ideal, but, shes gone way too paranoid. However, its a great thing for her, docs have been saying to stop for years now so I am not going to tell her her 'fears' are over the top when its resulted in this.
I was actually concerned about withdrawal from the alcohol her body was dependant on, but she got nothing worse than a few days of headaches and a bit of a sore stomach. Luckily. I hear alcohol withdrawal can be a bitch..
