Unfortunately it's all part of the life cycle. So enjoy what time you have on this earth and have no regrets saying "I would have liked to do that." Just do it if you're still able to. You're dead a long time and you're not coming back for a second chance.
My grand parents on my dads side my grandma passed after 60+ years of marriage. Grandpa just gave up you could see it in his eyes wasn’t a year later he died also. Funny how the work.
