Yeah, it's definitely odd watching my parents age and kinda sad too. I never really thought of my mom and dad getting old. They just always seemed immortal to me. My dad had a heart attack recently, which really drove it home that their time is limited. It started to scare me and now there's kind of a role reversal going on. I find myself telling my parents that they need to go to bed earlier. I tell my dad to eat more vegetables and if he gets something I think is unhealthy, I'll lecture him over it. I worry when he drives so sometimes I'll make him let me do it for him, etc. etc.
