Okay I agree, having enjoyable vacations during one’s career years is a good idea. It’s easier for some and more difficult for others, but should be considered the fruits of our labor.Of my dad and my uncles, maybe one of them is having a chance to enjoy his retirement.
One died young-ish from an accident and possibly a doctor's incompetence. One seemed to be in good health and kept working well past typical retirement age to maintain a certain lifestyle, and not long after retirement he got some rough news from the doctor. One retired because of a condition that was making it difficult to get around and do things. And another is a butthead who loves to mock and shout at certain people so I don't talk to him anymore.
Pushing all your fun vacations, whatnot, etc. until retirement is looking like a really bad idea to me. Use your time off and have some new experiences.
Now hear this, genetics are merely the blue print for our bodies. Genes that may make us more prone to a particular illness must be “turned on” so-to-speak to be expressed. Managing stressors and avoiding environmental toxins give us the best shot to keep them off. (Cliff notes version)
Be well!
