Sometimes a lot of us men think we are doing everything for the woman we love, but there is an aspect of a woman a man doesn't understand.

Don't get caught up in the 'look' thing. Sometimes, we as men and women, the first thing that attracts us to someone is their physical appearance, and that's not always a good thing because what's good on the outside is not always good on the inside.

Sometimes I've been to a party where no one spoke to me for a whole evening. The men, frightened by their wives or sweeties, would give me a wide berth. And the ladies would gang up in a corner to discuss my dangerous character.

Sometimes I wonder if men and women really suit each other. Perhaps they should live next door and just visit now and then.

Sometimes I don't even accept the simplest medical treatment, such as, for example, the anti-flu vaccine.

Sometimes astronauts feel a little ill or get minor scrapes. I trained as a crew medical officer to do basic treatment.

Sometimes, patients with serious mental illness, just as with other serious medical illnesses, require hospitalization. In the absence of available public or private hospital beds, there are few options.

Immortality Device has been tested and researched by medical researchers all over the world from time to time. They email me and told me what they found. I post their results sometimes on my site.

As a physician and as a pilot, I think it lets me be a pretty good translator having one foot in the medical world and one foot in the flying world. Sometimes when the medical guys come in and speak medical stuff to the pilots, the pilots really don't know what they're saying.

Sometimes I wish I could just take a lightweight bag on the plane but instead I've got to make sure I've got all my medical stuff. That can become a bit boring.

It's very difficult when you have $1.50 per day to spend on food and drink, but for people who live this reality, that money also has to cover medical expenses and education, fuel and shelter - sometimes for an entire family.

Even top caliber hospitals cannot escape medical mistakes that sometimes result in irreparable damage to patients.

Henrietta Lacks' cells are immortal. They are known as the HeLa cell line, and they have become deeply involved in all sorts of medical and genetic research - sometimes in the most unexpected ways.

Medicine sometimes snatches away health, sometimes gives it.

I think marriage can sometimes turn things into a business. It stops being about feelings.

Unfenced by law, the unmarried lover can quit a bad relationship at any time. But you - the legally married person who wants to escape doomed love - may soon discover that a significant portion of your marriage contract belongs to the State, and that it sometimes takes a very long while for the State to grant you your leave.

Sometimes divorce is better than marriage.

Someone asked me recently if marriage is 50-50 - it averages out to be 50-50, but sometimes it's 75-25, sometimes it's 90-10. In the end, it has to average out to be 50-50; that's how you support each other.

There's no formula that can make a marriage work. Sometimes two people just click.

Sometimes I bust out and do things so permanent. Like tattoos and marriage.

You work on it. You talk about it. You don't go out looking for greener grass; sometimes you have to water the grass that you have. And that's what marriage is. Sometimes it can be hard.

You will often be in despair. You will sometimes think it's the worst decision in your life. That's fine. That's not a sign your marriage has gone wrong. It's a sign that it's normal; it's on track. And many of the hopes that took you into the marriage will have to die in order for the marriage to continue.

Marriage is a feast where the grace is sometimes better than the dinner.

There's a difference between lust and passionate love. Lust can't just creep in. You'll not find it where true love exists, but it has power enough to shatter the world you've worked so hard to create with love, and sometimes, it suddenly changes how you perceived love to begin with. Love then doesn't live there anymore.
